Run the same initialization commands (using beforeEach) for This can be useful if, for example, you want to The function describe allows you to group related tests. The functions describe, it, and browser are provided by WebdriverIO. Several testing frameworks supported by WebdriverIO.ĭescribe ( ' A visitor without account ', function ()) Other programming languages supported by Selenium. WebdriverIO JavaScript bindings, but the general concept should carry over In this article we’re going to be using the
It can be programmatically controlledįrom a variety of programming languages. Visit a specific URL or interact with elements on the page. Selenium is a piece of software that can control web browsers, e.g., to make them Infrastructure is up and running, and that your units of code work well together. To just enough to give you the confidence that the deployment went as intended, that your
Unit tests that allow you to easily identify the source of a problem, should one occur. Safeguard: most of your code should be covered by In the widely-used testing pyramid strategy, end-to-end tests act more like a We assume you are familiar with GitLab, GitLab CI/CD, Review Apps, and running your app locally, e.g., on localhost:8000. With WebdriverIO, but the general strategy should carry over to other languages. Through the process of setting up GitLab CI/CD for end-to-end testing JavaScript-based applications For the scope of this article, we will walk you To write such end-to-end tests, and how to set up GitLab CI/CD to automatically run these testsĪgainst your new code, on a branch-by-branch basis. Layers of your application, from the frontend to the database. Having the computer run through a few simple scenarios that requires the proper functioning of all Where automated end-to-end testing comes in: However, looking at the freshly deployed code to check whether it still looks and behaves asĮxpected is repetitive manual work, which means it is a prime candidate for automation. Thus, when we use a dependency manager likeĭependencies.io, it can submit a merge request with an updated dependency,Īnd it will immediately be clear that the application can still be properly built and deployed. (or branch, for that matter), the new code can be copied and deployed to a fresh production-like liveĮnvironment, reducing the effort to assess the impact of changes. Review Apps are great: for every merge request What’s next End-to-end testing with GitLab CI/CD and WebdriverIO.
