[EclipseCon NA 2014] Integration tests for RCP made easy with SWTBot and TychoMickael Istria
https://www.eclipsecon.org/na2014/session/integration-tests-rcp-made-easy-swtbot-and-tycho
Although we live in a modular world, it will always make sense to write and run integration-tests that allow the testing of the whole application, and not just a module. These integration-tests are often the only way to test real usage scenarios that rely on multiple modules and that can be affected by other modules and by the packaging of your application.
Some recent improvements have happened in the Eclipse world to make it easier to produce and run integration tests for RCP applications, reducing significantly their cost while keeping their coverage high, and conformance to real use-cases and ability to spot bugs. This presentation will show how SWTBot Test Recorder can be used to speed up the creation of valid integration-tests against your RCP product, and how Tycho can be used to run it easily on any existing and packaged RCP application, the same as the one your users will get.

A Successful Magento Project From Design to DeploymentJoshua Warren
Magento is a complex open source eCommerce platform. It’s open source nature and welcoming community means anyone can pick it up, learn it and launch it. After working on over 300 different Magento sites in the past 6 years, however, I’ve learned that many of the misconceptions about Magento - it’s slow, hard to work with, buggy or unstable come from projects that were built by first-timers who weren’t aware of Magento best practices. In this tutorial, I walk you through the entire process of creating, testing and deploying a high-performing, fast Magento-based eCommerce website.

A lot of companies use the Magento 1 platform to power their eCommerce needs. So when they set out to build a major new version, the Magento team had significant pressure to deliver a modern, well-designed PHP-based system. This include a new architecture and a new database model.
In other versions of Magento (1.9) we were able to upgrade core files and with a few lines of code we were able to upgrade modules and admin accesses.
The migration process to Magento 2 it’s a complex process that includes migration of database data and migration of modules.
I want share mi experience to know what is the better way and tools to arrive our goal.
Charitable giving trends with mobile technologiesX.commerce
Savvy merchants and developers are integrating charitable causes into their mobile strategies to achieve strategic advantages, and non-profits are using mobile technology to reach new audiences and increase the funds they raise. We will address ways businesses can incorporate these causes with mobile strategies to drive both social impact and business objectives, and how non-profits themselves are innovating in the mobile space.
With mobile cloud computing come efforts to simplify its development. Creating apps for the mobile cloud is significantly different than developing apps for a native smartphone platform. This session is about design and architecture considerations, the essential tools and technologies, and the pitfalls to avoid when building mobile cloud apps.
Scanning barcodes and QR codes with mobile devices is booming. It’s a frictionless way to connect the online and offline worlds, and this discussion will cover the technology and best practices for leveraging code scanning in your mobile apps. We will introduce the RedLaser SDK as well.
Having a mobile presence is easy. What’s hard is deciding what to include, what it should look like, and how to build it in the first place. These are best practices, design tips, and resources for mobile sites and apps.
Creative complex commerce: Respecting the Customers’ brand while integrating ...X.commerce
New technology drives the need for new experiences. In this session, we’ll look at what the rise of open source means for retailers, and how retailers can take advantage of new technology such as Magento to deliver innovation. We’ll also discuss ways to enhance the user journey—from social to local and mobile commerce— while respecting the brand and avoiding lookalike sites. We’ll bring it all together through a case study from the B2B world that pushes the boundaries of traditional commerce.
Trending now and in the future: Social commerceX.commerce
Many companies are trying to tap into the 750 million potential shoppers on Facebook—and missing. That’s because social commerce is about more than just putting up a Facebook storefront and adding a Like button to your products. Social commerce vendors, brands, sellers, suppliers and developers need to know about the following: social shopping trends; social data integration with traditional ecommerce analytics; why Taste Graphs will overtake Social Graphs in influencing purchasing decisions, and how Facebook may emerge as a dominant micropayments platform.
Handling the boom in international commerceX.commerce
The world’s two billion Internet consumers are accessing U.S. markets through the web more than ever. In fact, one in ten U.S. ecommerce transactions already comes from international consumers. How have retailers been responding to this lucrative change in the landscape? What APIs, development languages, and payment technologies work best when dealing with foreign terms, currencies, and shipping implications?
The near future of real web applicationsX.commerce
There is a lot of noise being made about HTML5 as the new web technology to use and markets for apps as the best way to sell products and distribute applications to our end users. In reality there is not much new about it - all we are doing is treating the web as a distribution and sharing platform and browsers as the software to run our applications on. In this talk Christian Heilmann of Mozilla shows how in the near future application installation and in-app payments can happen on the most distributed market there is - the internet and through your browser. You will see how the technologies we build web sites in got an upgrade to allow us to build light-weight and focused applications that allow our end users to reach their goals faster and in a more re-usable fashion than with traditional ecommerce. Browsers and hardware are becoming more powerful each day, it is time to use that power in a sensible manner.
Proudly Found Elsewhere: The Open Source BonanzaX.commerce

The mighty cloud draws businesses and developers who seek its agility and productivity. But which type of cloud is best? We moved eBay Marketplace, a major eCommerce site, from a traditional infrastructure to a cloud model. We will present the strategic, technical and cost factors we weighed when deciding between cloud versus automation, and porting applications versus rewriting them. We will explain why we ended up with a hybrid: developing our own internal cloud while leveraging the massive infrastructure of public cloud providers.
If the web has taught us anything, it is that open systems, portability, and choice drive innovation. Similarly, the cloud era will be fueled by open technologies and a broad ecosystem. The OpenStack community was founded last year and has since become the fastest-growing open source cloud project, attracting hundreds of contributing developers and more than 100 participating companies. We will discuss how OpenStack is ending cloud lock-in by allowing enterprises and other service providers to run the same code that powers the Rackspace cloud. With a common platform, developers and businesses will be able to move applications among different clouds or their internal infrastructure. We will also go over use cases and options to consume OpenStack.
In 2011, we’re going “frictionless.” We will demo eBay’s latest seller innovations for seamless shipping. Our favorite new APIs enable you to scan any item with a mobile device and the recommended match for weight, dimension and service requirements populates the interface and even provides labels and tracking numbers.
Buyers appreciate the catalog experience; they certainly don’t miss the avalanche of item listings. Sellers also like providing catalog experiences; their items get more exposure. With eBay’s built-in product definitions, sellers don’t need to take valuable time writing product descriptions or item specifics or even providing photos—eBay’s built-in product definitions take goods quickly to market. New this year: creating your own product listing within the eBay catalog using UPC codes and brand MPNs.
Imagine a commerce world where thematic and seasonal stores could automatically pop up and then disappear with minimal editorial work. Here we talk about the underlying platform that enables mining large-scale user behavior and query data to set up stores automatically based on themes of interest, and emerging and buzz-creating topics. We will describe the science and tools to build experiences that would drive commerce through custom experience and social media, and help sellers, shoppers, and the enthusiasts.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

[Greetings]Who of you are Magento developers who customize Magento for their clients or implement Magento extensions? (hands)Good! *You* are the intended audience for this topic.The topic is – integration tests in Magento – intended for developers who would like to try automated tests in Magento and possibly start writing tests for their own Magento extensions TODAY.
1) We’ll start from an overview of automated test types. What are the goals and how they are different.2) Then we’ll stop by on integration tests more in detail.3) I’m going to demonstrate integration testing framework in Magento and explain and how to use it.4) Then developers who are interested in creating tests, may find useful an explanation of the framework design.5) Finally, we’ll see where to get Magento integration tests and their documentation.So let’s proceed with overview of automated tests.
Automated tests is essential part of contemporary software, especially of large products. Development teams implement automated tests along with the product and put them on rails of continuous integration to ensure that several important concerns are addressed:1) Whether features of the product work as intended.2) Whether it is reliable.3) Does it perform good enough.4) And whether it is compatible with intended environments.
Functional tests is the most high-level type. Using functional tests, the product features are tested in the way as if user would interact with the system.The simplest implementation of functional tests is “manual”: a human (QA engineer) actually interacts with the system by a defined scenario or combination of multiple scenarios. Automation of these tests is usually implemented by recording QA engineer interaction with the system and then refining it with variables, that would allow to run these tests later on, automatically on different environment.
Performance testing is a special approach, when certain functional test (or we can call it “business scenario”) is executed multiple times in various environment conditions and various frequency to determine performance bottlenecks.There is a great variety of performance tests. For example:1) “Performance” tests execute the same scenario on regular basis and compare results over time2) “Load” tests assure that scenario runs successfully under normal and peak loads3) “Capacity” tests allow to determine the practical limit of algorithm load, while scenario executes successfully4) “Stress” tests inspect system behavior when scenario fails under enormous load
Unit tests are supposed to verify small portions of algorithm by executing its code with different combinations of arguments and asserting return values.Unlike functional tests, the unit tests are written by programmers and *for* programmers. They are to be used every day as a safety net when modifying code to preserve algorithm stability and backwards compatibility.Developing code along with unit tests cultivates better programming skills and results in better designed code.
Static code analysis tests perform syntax analysis of the source code without executing it to determine whether it is implemented according to coding standard and certain conventions.Like unit tests, this is also a “programmer-oriented” type, which helps team of developers to follow common standard, when working on source code together.There are tools for programming languages, that allow to perform static code analysis. For example Magento 2, as it is implemented on PHP, uses 3 tools:- PHP CodeSniffer – to enforce coding standard- PHP Mess Detector – to determine poor-designed code- PHP Copy-Paste detector – well, to detect copy-paste
Now let’s take a closer look at a different type of automated tests – integration tests.
The goal of integration tests is to execute programming code, deployed on close to real environment. In other words, in integration tests the product is *intended* to interact with environment.This type of tests concentrates on how the system works as a whole, rather than how its modules or *layers* would work by their own. It doesn’t aim to execute all combinations of algorithm – in integration tests it is enough to execute the code by “critical path”.A good example of interaction with environment is to run the same test suite, deployed on different DB platforms. Of course if the application has DB abstraction layer.* “Critical path” term in graph theory is the path of maximum length in an oriented acyclic graph. So if to consider an algorithm as such graph, in integration tests we want to execute the maximum amount of code in one pass.
Integration tests bring up value, a bit different from other types of tests.From business prospective, the integration tests can give measurement of “how stable the product is”. The user or product owner may not want to see detailed report of code coverage, they may prefer something simple, like one number. Percent of code coverage by integration tests can be this simple number, that gives some general idea about product stability.Integration tests have nature similar to unit tests, because they execute code in similar way. But they also allow to discover bugs, dependent on certain environment. Otherwise such bugs would emerge after product release, on customer environments, which is not a pleasant situation.
Unlike in unit tests, the less environment and objects are mocked during execution, the better it is for integration tests.Execution of unit tests has narrow scope of a module or class, while integration tests pierce through system architectural layers and touch as much modules as possible.
This is what kind of interaction with environment to expect when running integration tests:1) Before running test suite the product is to be deployed and installed2) It should interact with real database3) It is to utilize file system and all kind of caching
A use case from Magento 2 project.Magento is a product that supports multiple database platforms. Use of integration tests in continuous integration process allows to spare efforts of programmers from having to verify their code on all platforms all the time.A programmer can develop on his favorite DB platform, while continuous integration will execute integration tests on all platforms (and report errors).
So this kind of integration testing is implemented in Magento 2 by a test suite that works on “integration testing framework”.Let’s see how this framework can be used: we’ll review initial configuration, setup environment and then run the test suite.
Magento integration testing framework is built on top of PHPUnit framework, therefore the latter needs to be pre-installed. The PHPUnit version 3.5 or later is needed.Before running test suite, Magento application instance will be automatically installed into an empty database. And to operate, Magento requires a writable folder to store its cache and logs.
Integration tests and framework reside in “dev/tests/integration” folder, relative to Magento application root.Here we distinguish several major areas:1) The test suite – a folder where we can find a set of regular PHPUnit test cases, which are direct descendants of “PHPUnit_Framework_TestCase” class. One of key points in Magento integration tests is that we tend to stick with standard PHPUnit features as much as possible.2) Under “framework” folder there is “bootstrap.php”, a traditional thing to use with PHPUnit. And under “framework/Magento” there are classes, that implement Magento-specific PHPUnit customizations. The “framework/tests” folder contains unit tests for the integration testing framework, it has no relation with the integration test suite.3) Also there are configuration XML-files, which are used to customize Magento application framework. We’ll stop by on them in next slides.4) The “tmp” folder is that writable folder I mentioned before. Magento application instances are actually stored in “tmp” sub-folders.
PHPUnit features a fallback mechanism for configuration files. When you run “phpunit” from command line, it searches for “phpunit.xml” file or, if not found, for “phpunit.xml.dist” file. This allows to fiddle with configuration: out of the box Magento integration tests have some default presets in the “.xml.dist”, which can be locally overridden by copying it as “.xml” file.Integration testing framework replicates this behavior for “etc/local.xml” files.
Before running tests first time we start from setting up configuration in phpunit.xml. The PHPUnit framework allows to define constants in this file and use them in tests source code.There are a few such custom constants:1) “TESTS_LOCAL_CONFIG_FILE” specifies path to Magento local.xml configuration prototype, which contains database credentials2) The “TESTS_GLOBAL_CONFIG_FILES” and “TESTS_MODULE_CONFIG_FILES” allow to adjust the way how Magento reads configuration. Out of the box it says to load all XML-files from the specified folders3) “TESTS_SHUTDOWN_METHOD” is an optional constant, that allows to specify whether to uninstall or “restore database” after test suite execution. “Uninstalling” means a full cleanup of database and its temporary folder, “restoreDatabase” will result in pumping in the first database dump, that was created before executing tests first time.4) Also there are optional constants, that allow to collect profiling results in a CSV-file and use it, for example, to build some performance metrics.
Credentials for database, where application will be installed in, are specified in the “etc/local-<vendor>.xml” files, which are prototypes for Magento local.xml files.Note that besides section with DB credentials, this file also contains information about installation date and encryption key. It is important to not modify them, because valid installation date and encryption key values indicate that application is already installed and there is no need to run SQL-setup scripts.
Now we know enough to run integration tests.
Now that we know how to run integration tests in Magento, let's see from programmer's standpoint why there was need to build something on top of PHPUnit framework and how it is designed.
The first what integration testing framework does is bootstrapping Magento application. A fully-automatic installation, full cleanup or just database restoration. Entry point for this is the “framework/bootstrap.php” file, which has “Magento_Test_Bootstrap” under the hood. Besides of performing bootstrapping routines, this object can disclose customized paths to writable folders, where application stores cache and temporary files.Magento_Test_Db classes are database adapters, that are used by bootstrap for dealing with database cleanup and handling backups.
Executing a lot ofMagento code in one scoop without mocking anything is a quite challenging task:- there is application object with certain state,- some code may rely on certain configuration state,- and there is code that relies on objects, existing in database.To address these difficulties and simplify programmer’s task, the integration testing framework has a “Listener” – a standard way to customize PHPUnit framework behavior. As you may know, the PHPUnit framework utilizes PHPDoc annotations to execute some additional commands.So Magento_Test_Listener class aggregates custom PHPDoc annotations, that implement useful Magento-specific testing features.
@magentoAppIsolation annotation specifies to reset state of registry, re-instantiate application object and partially cleanup cache.Cleaning up global objects manually without this annotation would increase code complexity, especially that programmer would have to implement try-catch code blocks everywhere, because PHPUnit assertion can throw an exception. This example illustrates how compact can a test be in virtue of @magentoAppIsolation.This directive can be specified for tests (methods) and has “enabled” and “disabled” values, “disabled” by default. Isolation cleanup is performed automatically before executing test case classes.
To get into some conditional block, which is on critical path of algorithm, sometimes a system configuration value needs to be set up first. That’s a lot of code, especially considering the “try-catch” necessity.The @magentoConfigFixture annotation purpose is to tackle this problem: it allows to set system configuration value before test and reverts it back after test is complete (regardless of it failed or not).It can be specified on test case level or test level, or both (test level overrides test case level). A value can be set directly into global configuration, “current” store view configuration or other specified store view.
Some tests make sense only when there is an object existing in database, so that it can be loaded and asserted. Creating and persisting an entity would obfuscate and complicate the test, and again – the programmer would face with the “try-catch” problem when data is to be reverted.In this case the @magentoDataFixture directive comes for help. It works like an “include” script just wrapped into a database transaction:- Start transaction before including the script- Run the test- Revert transaction after test is executedOne important thing to know when composing such a script: use only the application API. No interaction with database directly. This will make tests more durable against database structure changes and independent from specific DB vendor.
The integration testing framework also contains a few utility classes, that would help to develop certain types of tests:- Abstract controller test case – allows to dispatch Magento controller actions, assert redirects and 404 result, as well contains HTTP-request and response stubs- Magento_Test_Entity is a helper to test CRUD operations with a typical model-entity, that is based on “Mage_Core_Model_Abstract” Other classes include special test suite that allows to exclude test groups using list of enabled/disabled Magento modules, a base class for code integrity tests and other smaller helpers.
An example: testing controller actions using “Magento_Test_TestCase_ControllerAbstract”. Among invoked methods, we can see a few custom ones, introduced by this class:- dispatch() – allows to dispatch a controller action by specifying just request URI- assert404NotFound() – analyse response (stub) object to determine whether it has 404 status- assertRedirect() – assert the response stub object for redirect- And there are getters and setters for request and response objects
Another example demonstrates how to use Magento_Test_Entity.- Constructor requires a Mage_Core_Model_Abstract instance (which represents an entity) and an array with data to change and assert during “update” part of the test- The “testCrud()” method starts test and assertions.It consecutively attempts to perform the following actions:1) Persist object in database and assert its new ID (the “create” operation)2) Read object from database by this ID3) Update object data from the passed array and persist it in database as “update” operation4) Delete the object from database.
Separately I’d like to mention code integrity tests. This is a sub-type of integration tests, that scan entire code base and verify compliance with certain framework feature.For example, the system has template engine and its components may introduce templates. A code integrity test would scan entire code base for templates declaration and verify whether they exist, execute them and check whether they don’t produce errors.Another example – scanning view files for references to static resources, such as images, CSS and JavaScript files and verifying that these files are accessible. Such test helps to find and eliminate broken references.The primary difference of code integrity tests from static code analysis is that code is executed in the process: the code works as an instrument to test itself.
A few last notes for programmers who would like to start implementing own integration tests.1) Always keep in mind the isolation problem: integration tests interact with environment, but still they should be isolated between each other.2) When dealing with fixtures or data providers, never perform direct operations with database. Otherwise tests will be more fragile.3) Keep performance of tests adequate to running on a local developer’s machine.
At this point I’ll just announce where to get the integration tests and framework, and documentation.
The code is publicly available in Magento 2 project. Here you can see Magento 2 SVN public repository URL.But soon it will be gone. We already internally have switched to Git and soon will replace this link with a URL to Git repository.Stay tuned.
Documentation for integration tests is available in product documentation wiki space, developer’s guide. There are several integration test guides, which are part of general-purpose “Magento Automated Testing Guide”.These documents have all the same information I presented today, just more detailed.The link will be announced, as soon as we deploy it on public server. Our sysadmins are working on it right now.
