In this case do I need to write a captor for each argument in spite of the fact I need to capture only the first argument?
durron597's answer is correct—you do not need to capture all arguments if you want to capture one of them. One point of clarification, though: a call to ArgumentCaptor.capture()
counts as a Mockito matcher, and in Mockito if you use a matcher for any method argument you do have to use a matcher for all arguments.
For a method yourMock.yourMethod(int, int, int)
and an ArgumentCaptor<Integer> intCaptor
:
/* good: */ verify(yourMock).yourMethod(2, 3, 4); // eq by default
/* same: */ verify(yourMock).yourMethod(eq(2), eq(3), eq(4));
/* BAD: */ verify(yourMock).yourMethod(intCaptor.capture(), 3, 4);
/* fixed: */ verify(yourMock).yourMethod(intCaptor.capture(), eq(3), eq(4));
These also work:
verify(yourMock).yourMethod(intCaptor.capture(), eq(5), otherIntCaptor.capture());
verify(yourMock).yourMethod(intCaptor.capture(), anyInt(), gt(9000));

When it comes to UI components, there are two versatile methods that we can use to build it for your website: either we can use prebuilt components from a well-known library or framework, or we can develop our UI components from scratch.
The sky’s the limit (and even beyond that) when you want to run test automation. Technology has developed so much that you can reduce time and stay more productive than you used to 10 years ago. You needn’t put up with the limitations brought to you by Selenium if that’s your go-to automation testing tool. Instead, you can pick from various test automation frameworks and tools to write effective test cases and run them successfully.
“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.
In an ideal world, you can test your web application in the same test environment and return the same results every time. The reality can be difficult sometimes when you have flaky tests, which may be due to the complexity of the web elements you are trying to perform an action on your test case.
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.
