Unit Testing is Overrated • Oleksii Holub
As Russia wages a genocidal war against my country, I'm grateful to everyone who continues to stand with Ukraine in our fight for freedom. The importance of testing in modern software development is really hard to overstate. Delivering a successful product is not something you do once and forget about, but is rather a continuous and recurring process. With every line of code that changes, software

GitHub - rr-debugger/rr: Record and Replay Framework
rr is a lightweight tool for recording, replaying and debugging execution of applications (trees of processes and threads). Debugging extends gdb with very efficient reverse-execution, which in combination with standard gdb/x86 features like hardware data watchpoints, makes debugging much more fun. More information about the project, including instructions on how to install, run, and build rr, is
rr: lightweight recording & deterministic debugging
what rr does rr aspires to be your primary C/C++ debugging tool for Linux, replacing — well, enhancing — gdb. You record a failure once, then debug the recording, deterministically, as many times as you want. The same execution is replayed every time. rr also provides efficient reverse execution under gdb. Set breakpoints and data watchpoints and quickly reverse-execute to where they were hit. rr
GitHub - DATA-DOG/go-sqlmock: Sql mock driver for golang to test database interactions
sqlmock is a mock library implementing sql/driver. Which has one and only purpose - to simulate any sql driver behavior in tests, without needing a real database connection. It helps to maintain correct TDD workflow. this library is now complete and stable. (you may not find new changes for this reason) supports concurrency and multiple connections. supports go1.8 Context related feature mocking a
Just-API
Just-API Just-API is a declarative, specification based test framework for REST, GraphQL (or any HTTP-based) APIs. Users can test APIs without writing code, but they can also tap into code when they want to. It reads API test specification from YAML files and runs them in serial/parallel mode. Test reports can be generated in several formats including HTML and JSON. In simple terms, users build a

Evolving Test Practices at Microsoft - Azure DevOps | Microsoft Docs
Testing helps ensure that code performs as expected, but the time and effort to build tests takes time away from other tasks such as feature development. With this cost, it's important to extract maximum value from testing. This article discusses DevOps test principles, focusing on the value of unit testing and a shift-left test strategy. Dedicated testers used to write most tests, and many produc
