The Key to DevOps? Testing Early in the PipelineDevOps.com
As teams embrace DevOps, quality becomes a bottleneck for rapid development and delivery. Traditional QA practices of functional testing release candidates are not cutting it in this new era of lightning fast development. Teams are finding that they need to test early and often to rapidly surface error during development to reach continuous delivery.
Learn how to implement E2E testing at the earliest stages of development: from initial code commit, to pull requests with ephemeral environments, and high confidence merges. This practice optimizes DevOps software development by enabling developers to solve issues earlier, proactively update tests (so they don’t break later) and become even more productive.

API testing is a critical component of the whole testing process. It deals with testing the business logic of an application, which is typically encompassed in the business layer and is instrumental in handling all the transactions between user interface and underlying data. It is deemed as a part of Integration testing that involves verification of functionality, performance and robustness of API’s.
The promise of DevOps is that we can push new ideas out to market faster while avoiding delivering serious defects into production. Andreas Grabner explains that testers are no longer measured by the number of defect reports they enter, nor are developers measured by the lines of code they write. As a team, you are measured by how fast you can deploy high quality functionality to the end user. Achieving this goal requires testers to increase their skills. It’s all about finding solutions—not just problems. Testers must transition from reporting “app crashes” to providing details such as “memory leak caused by bad cache implementation.” Instead of reporting “it’s slow,” testers must discover “wrong hibernate configuration causes too much traffic from the database.” Using three real-life examples, Andreas illustrates what it takes for testing teams to become part of the DevOps transformation—bringing more value to the entire organization.

EMA/Apica October 2016 Event: User Environment Management For Digital Transfo...Apica
Both User Environment Management (UEM) and Digital Transformation (DT) are current industry buzzwords. However, the two are more interrelated than most recognize. During an October 2016 event Julie Craig, research director from analyst firm Enterprise Management Associates, addressed these two trends and discussed ways in which UEM– and specifically synthetics solutions such as Apica– supports and facilitates DT initiatives.
For most organizations, new technologies are coming to market faster than we can keep up with. This wave of innovation brings with it new opportunities for cutting-edge applications and services that create industry differentiation. At the same time, the complexity of melding new technologies into existing production systems makes it difficult to chart a course through the flood of possibilities these technologies have to offer. As a result, many companies deploy new applications first, then figure out how to manage performance and availability.
In other words, performance optimization is too often an afterthought.
At the recent STPCon Spring 2017 held March 14-17, Capital One's Eli Stull gave the closing keynote. His presentation focused on performance testing in the evolving API economy.

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).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Basic Definitions
1. Non-Functional Requirements
The non-functional requirements for performance explain how an IT system should perform in a production-
like environment.
A typical requirement is response time per page or the transaction at a specific load.
3. 33 www.apicasystems.com
2. Performance Risk Assessment
A performance risk assessment is a task that is done to determine if there are any
performance risks with a new release, architecture change, or increase in number-of-
users.
The task is often done as a workshop with IT architects, developers, DBA's,
operations, test management and other stakeholders.
The output from a performance risk assessment is a report that outlines the risks (if
any) and the recommended performance tests to minimize any risks.
The report might also include requirements on test environments, test data and an
estimation of the time/costs to perform the tests.
Basic Definitions

3. Performance Test
A performance test is done to verify that an IT system performs according to the non-functional
requirements.
If non-functional requirements are not available a performance test can be done to verify the actual
performance before a release.
4. Virtual User – VU
A virtual user is a simulated real user used in a performance test.
Basic Definitions

5. Infrastructure Monitoring
Infrastructure monitoring is monitoring of server and middleware performance metrics.
Examples of metrics are CPU utilization, Memory usage, Disk usage, and the number of idling threads in
a thread pool etc.
Basic Definitions
6. 66 www.apicasystems.com
6. Application Performance Management – APM
Application Performance Management is monitoring and management of application
performance.
The performance of an application can be monitored at each level from the client
(end user monitoring) through distributed transactions and including the platform.
The monitored distributed transactions flow can be used to visualize the flow through
each tier and to do an end user response time breakdown.
Example products are AppDynamics, DynaTrace and New Relic.

7. Performance Test Scenario
A performance test scenario is a placeholder for everything that relates to a performance test. One of the
benefits of a performance test scenario is that everything is handled in one place, making it easy to rerun
a test or use a scenario as a template.
– One or more performance test scripts
– Parameter files
– Parameters that control how the load is applied
– Infrastructure monitor agent configuration
– APM integration configuration
– Test result name

Test Case Definitions
1. Test Case
A test case can be functional or non-functional and describes in detail each step and interaction
with an application. If the application has a user interface the test case usually describes the
most common interaction that a real user would do. A functional test case can often be adopted
to a non-functional test case by removing unnecessary steps that are not directly related to
performance.
2. Test Case Transaction
A test case transaction is used in performance test scripts to monitor single or multiple HTTP/S
calls.
Note: A test case transaction is independent of calls that relate to a web page. They are also
used for applications without user interfaces, such as web services.

1. Transaction
A transaction is a single call/response using a specific protocol such as HTTP/S.
2. Performance Test Script
A performance test script is a script that generates transactions. A performance test
script can be simple with a single transaction or complex with a large number of
transactions.
3. Transaction Response Time
The time it takes for a single transaction, including receiving the response.

4. Page Response Time Server Side
The time it takes for all calls that are done to render a web page. Note that calls can be both in serial
or in parallel.
5. Page Response Time Client Side
The time it takes all calls to reach the server in a specific web page, including the time it takes to
execute client-side code and rendering a complete web page.
6. Think Time
Think time is the time between one user interaction to the next user interaction that in turn creates a
new call to the server.
If the application does not have a user interface it is the time between two calls or between two
test case transactions.

7. Background load
Background loads are transactions that are generated to put load on the system. The
system has a similar total load as expected in production together with the
transactions that are tested.
8. Peak Load
Peak load is the highest expected load on a system during a shorter time period.
The peak load is defined as transactions, pages, iterations or test cases per second.

9. Throughput
Throughput is the number of specific transactions per second and the unit is
transactions per second TPS.
10. Response Time Analyze
A response time analyze is done to determine min, avg. and max response times for
a specific throughput of a transaction, a test case transaction, or a complete web
page.
This analysis can also be done to find the point (if any) where the response time
increases due to an increase in throughput.

Performance Test Type Definitions
1. Load Test
A test that generates transactions to a targeted application with intention of verifying
how the application reacts to a specific load.
2. Base Line Test
A load test with a specific level of load to be used as a baseline when comparing
application releases or infrastructure changes.
The goal of baseline test is to generate a test result that can be used as a reference
when comparing performance between releases, configurational changes or changes
in HW or SW versions.

3. Stress Test
A stress test is a performance test where the level of load is increased over the
expected load in production.
The focus of the test can be to see how a specific function is handling high-load or as
a test that generates production-like transactions with a higher than expected
throughput.
The goal is to identify what part of the architecture design is limiting the performance
and if the application recovers when the load is decreased.

4. Stability Test
A stability test is done to test the stability of an application over time. The load is often set to 80% of max
throughput and the test time is set to 8-10 hours.
The goal is to find out if there are resources that are not handled correctly by the application. Examples
are memory leaks, or connection pools that run out of connections etc.

5. Scalability Test
A scalability test is done to determine how well an application is handling an
increased load and how well it utilizes the HW platform.
Typically, a scalability test is done without any think-time and with a slow ramp-up of
the load.
A perfect (theoretical) application does not show any increase in response time when
the load is increased until a specific point where the response time increases rapidly.
A more realistic application has a small increase in response time during a ramp-up
of the load and then at a specific point a steep increase.
An application that is not scaling has a significant increase in response time linear
with the increased load.

6. Concurrency Test
A concurrency test is done to determine the performance of a system using
concurrent transactions that are expected to load the system in production.
The goal is to determine if there are transactions that affect each other due to shared
resources or synchronizations.
