When speaking with people who enter IT, I often mention manual testing as an option for an entry-level job. In this article, I’ll explain what manual testing is, how it fits into the development process, what skills you need, and how this skill can help you on your path to…

End-to-end (E2E) testing requires that many things be in just the right place for it to work as expected. In this article, I’ll walk you through all the necessary pieces of a successful E2E setup. Docker Docker is a platform that allows developers to build, share, and run containers-well-defined, isolated environments…

Unit tests are part of the software development drill. At the same time, the benefits of writing them can be unclear, especially when you’ve never worked on a project with a decent test coverage. …

For stable end-to-end (E2E) tests, we need an environment that is as isolated from the outside as possible. Reduce flakiness Flaky tests are tests that fail for reasons unrelated to your code. They make it difficult to use E2E as a reliable check for the correctness of the application. In extreme cases…

In this article, we will take a look at some possible solutions to problems that appear if you adhere to the discipline of creating end to end (E2E) tests. As you continue developing an application, it will inevitably become more complicated and include more features. Maintaining the same E2E coverage…

In this post, we will discuss the common pain point in developing an end-to-end (E2E) test suite: the flakiness. Flaky tests are tests that fail even though they should pass. …

Adding end-to-end (E2E) tests to your application from scratch is a lot of work. Building a complete test suite will be a long project, so it makes sense to prioritize wisely which use cases get covered first. In this article, I will demonstrate the testing approach I’ve been using successfully…

In the previous article, we took a look at all the edge cases one can find in a simple operation: dividing two numbers. Now, let’s improve all those aspects of the application. Deciding on trade-offs Often, the challenge in programming is choosing one of many imperfect solutions. The choice depends on the use…

There is a big difference between an application that works OK only in a perfect situation and one that behaves as expected in all circumstances. For the user, the former gives the appearance that the product is almost ready-with some bugs here and there. In reality, making the application reliable…
