The tests are very fragile since there are many moving parts. The previous examples of Spock unit tests will cover most of your testing needs. Product news, interviews about technology, tutorials and more. Ideally, you should use full sentences to explain what each block does in a high-level manner. How can we replicate this processing in our unit test? Cela fonctionne aussi pour SqlException aussi: ConstructorInfo ci = typeof (SqlErrorCollection). This time, we have the following blocks: given, when, then, and. As a grand finale, we will see an extreme unit test where the answer of a mock depends on the argument. The test result shows the title correctly as a full English sentence. Why do need mock/stub? Spock makes a clear distinction between the two as mocks and stubs, as we will see in the sections to follow. The stubs and mocks follows Martin Fowlers definition of stubs and mocks. You are forced to add more testing frameworks into the mix, each one with its own idiosyncrasies and issues. The underscore character is a special character in Spock, and it means “any”. You might have already noticed that our CustomerReader class is not correct, as it does not handle the null case, i.e. If any of these statements is false, the whole test will fail.
