Sometimes, in our test code, we need to handle actions that apparently could not be done automatically. For example, some mouse actions such as context click, double click, drag and drop, mouse movements, and some special key down and key up actions. These specific actions could be crucial depending on the project context.
Hey Testers! We know it’s been tough out there at this time when the pandemic is far from gone and remote working has become the new normal. Regardless of all the hurdles, we are continually working to bring more features on-board for a seamless cross-browser testing experience.
“Test frequently and early.” If you’ve been following my testing agenda, you’re probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. I’ve encountered several teams who have a lot of automated tests but don’t use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.
Hey LambdaTesters! We’ve got something special for you this week. ????
JUnit is one of the most popular unit testing frameworks in the Java ecosystem. The JUnit 5 version (also known as Jupiter) contains many exciting innovations, including support for new features in Java 8 and above. However, many developers still prefer to use the JUnit 4 framework since certain features like parallel execution with JUnit 5 are still in the experimental phase.
