You are writing some automated tests with Selenium, that require you to fill in some text fields in a form. You are pretty confident you typed the values you expected to type, into the field you expected to type into. But, here are just 3 reasons why you should write some code that checks that you actually wrote what you thought, where you thought, before submitting the form you are trying to fill in.
When automated test are running, they are either running on your own machine (when you write them or run them to check something), or in your CI.
When you run the test on your machine, if there are failures, it might be easy for you to look at what is running (if you have some visual tests, that interact with either browsers or apps on your machine). You can just rerun a failed test and visually inspect for failure reasons. But, if tests are running on a CI machine, visual inspection is either very difficult or even impossible. You might not have access to connect to that machine, or to see how tests are being run. Continue reading Test design: write tests with proper console output to easily identify failure reasons
Automated tests are used to validate features in development environments but also in production. Whereas the classic approach of keeping all tests in the same code project is the most popular, it is not the best idea (and by code project i mean for example a Maven project). Continue reading Better Test Code Principles: #4 Keep your production tests separate from your dev environment ones
When i look at a test class, what i want to see is clean code. What i mean by that is, well a few things, but the most important one: i want the test class to hold the code for the tests, not the code for everything but the kitchen sink.
When we write tests we have a lot of data to prepare for them. Whether this is the ‘expected’ or the ‘actual’ data used in the tests, or some auxiliary code that we need, there always is some processing that needs to be done, apart from the actual asserts that a test should do. What the test class should contain is only the checking / asserting part, while having specialized classes generate all the data that is required in the test. A test class should only check the actual data against the expected data. This is the separation of concerns principle. Continue reading Write clean code for your tests by using the separation of concerns principle
So this year’s edition of RTC (Romania Testing Conference), held in Cluj-Napoca, has just concluded, and as a participant and speaker i had a great time attending the event. Therefore, here are some impressions and takeaways from a full day of presentations and meeting some really lovely folks. Continue reading Impressions after the Romania Testing Conference 2016
Suppose you are starting work on a new piece of software that you will need to write automated tests for. Your goal is to cover the most relevant test scenarios that apply to the feature , without missing or forgetting one. Below are a few steps (guidelines) to help you achieve identifying those required scenarios (a sort of ‘how i do it and it works for me’ guide). Continue reading How to identify the test scenarios you have to automate
Idea just released a major update to their IntelliJ IDE, which contains loads of fixes, enhancements and new features. The UI improvements on the testing side are quite interesting and useful (as they specify on their blog, this part has been completed rewritten, resulting in a much smoother and better working UI). Some examples of the interesting features this upgrade brings are presented below (for running TestNG tests): Continue reading IntelliJ 15 gets released with improved UI for testing
