This document provides an overview of software testing techniques, focusing on black-box testing. It defines software testing as verifying that a software product meets requirements and identifying bugs. The two main types of testing are black-box testing, which ignores internal code structure, and white-box testing, which considers internal structure. Six types of testing are discussed: unit testing examines individual code units; integration testing verifies code units work together; functional and system testing ensure requirements are met; and stress, performance, and usability testing evaluate non-functional properties. Acceptance testing involves customers verifying requirements are fulfilled.

Test Automation
Test automation is the use of test automation software like Selenium or self-developed testware to execute test cases.
Test automation is mostly used to automate repetitive testing tasks in a formalized way. It is also used to execute tests that would be difficult to perform manually like performance testing.
There are many advantages of test automation that are mostly related to the repeatability of the tests and the speed of test execution. There are a lot of commercial and open source tools available which can be grouped into two main categories; Code-Driven and Graphical User Interface Testing. Thus the key success factor in test automation is selecting the right tool and have a specialized test automation team.
It is to use test automation tools by considering ROI (return on investment). Otherwise it is quite easy to waste big amount of energy, commitment and definitely money.

Test Otomasyonu:
Test otomasyonu özellikle tekrarlayan ve manuel olarak yapılması zor olan testlerin Selenium gibi test otomasyon araçları kullanılarak ya da özel olarak geliştirilen test otomasyon scriptleri ile yapılmasıdır. Bu bakımdan:
- Regresyon testleri
- Performans testleri
- Yük ve Stres testleri
- Test yönetimi
test otomasyonuna en uygun test tipleri ve aktiviteleridir.
Test otomasyonunun en büyük faydaları:
- testlerin hıznının artırılması
- testlerin kapsamının artırılması
- testlerin doğruluğunun artırılması
- testlerin raporlama kalitesinin artırılmasıdır.
Test otomasyonu doğru araç seçimi yapılmaması, ya da test otomasyonunu bilen uzman bir ekip tarafından yapılmaması durumunda faydadan çok zarar getirmektedir.

Everything You Need to Know About Unit Testing in Test Driven Development (TDD) with Case Studies!
TDD can be defined as a programming practice that instructs developers to write new code only if an automated test has failed. This avoids duplication of code.
The primary goal of TDD is to make the code clearer, simple and bug-free.

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:

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).

Black box testing
1. Testing Overview and Black-Box Testing Techniques
Software testing is an important technique for assessing the quality of a software product.
In this chapter, we will explain the following:
• the basics of software testing, a verification and validation practice, throughout
the entire software development lifecycle
• the two basic techniques of software testing, black-box testing and white-box
testing
• six types of testing that involve both black- and white-box techniques.
• strategies for writing fewer test cases and still finding as many faults as possible
• using a template for writing repeatable, defined test cases
1 Introduction to Testing
Software testing is the process of analyzing a software item to detect the differences
between existing and required conditions (that is, bugs) and to evaluate the features of
the software item [9, 12]. Software testing is an activity that should be done throughout
the whole development process [3].
Software testing is one of the “verification and validation,” or V&V, software practices.
Some other V&V practices, such as inspections and pair programming, will be discussed
throughout this book. Verification (the first V) is the process of evaluating a system or
component to determine whether the products of a given development phase satisfy the
conditions imposed at the start of that phase [11]. Verification activities include testing
and reviews. For example, in the software for the Monopoly game, we can verify that
two players cannot own the same house. Validation is the process of evaluating a system
or component during or at the end of the development process to determine whether it
satisfies specified requirements [11]. At the end of development validation (the second V)
activities are used to evaluate whether the features that have been built into the software
satisfy the customer requirements and are traceable to customer requirements. For
example, we validate that when a player lands on “Free Parking,” they get all the money
that was collected. Boehm [4] has informally defined verification and validation as
follows:
Verification: Are we building the product right?
Through verification, we make sure the product behaves the way we want it to. For
example, on the left in Figure 1, there was a problem because the specification said that
players should collect $200 if they land on or pass Go. Apparently a programmer
implemented this requirement as if the player had to pass Go to collect. A test case in
which the player landed on Go revealed this error.
Validation: Are we building the right product?
Through validation, we check to make sure that somewhere in the process a mistake
hasn’t been made such that the product build is not what the customer asked for;
validation always involves comparison against requirements. For example, on the right
in Figure 1, the customer specified requirements for the Monopoly game – but the
programmer delivered the game of Life. Maybe the programmer thought he or she
