Testing is an essential daily practice for coding, providing a method to define desired behaviors for functions while ensuring code integrity. The article outlines how to set up ScalaTest for Scala 3 in a project by adding the library to the build file. It emphasizes creating tests using the FunSuite style, illustrating the test process with arithmetic functions. The author briefly explains the Arrange, Act, Assert pattern for structuring tests, indicating the importance of each phase in ensuring effective and clear testing.
In ScalaTest, a well-structured test case follows the Arrange, Act, Assert pattern, ensuring clarity in creating tests and validating outcomes.
Adding ScalaTest to the project involves including the library dependency in build.sbt, allowing for comprehensive testing within Scala projects.
Using the FunSuite style, we can implement various test cases including successes, failures, and exceptions to thoroughly evaluate our arithmetic functions.
ScalaTest offers a range of testing styles, allowing developers to select one that best suits their project's needs, enhancing testing flexibility.
