How do you do unit testing when you have
To give an example, imagine testing a CSV-reader (I just made up a notation for demonstration),
def test_readCsv(): ...
@dependsOn(test_readCsv)
def test_readCsv_duplicateColumnName(): ...
@dependsOn(test_readCsv)
def test_readCsv_unicodeColumnName(): ...
I expect sub-tests to be run only if their parent test succeeds. The reason behind this is that running these tests takes time. Many failure reports that go back to a single reason wouldn't be informative, either. Of course, I could shoehorn all edge-cases into the main test, but I wonder if there is a more structured way to do this.
I've found these related but different questions,
UPDATE:
I've found TestNG which has great built-in support for test dependencies. You can write tests like this,
@Test{dependsOnMethods = ("test_readCsv"))
public void test_readCsv_duplicateColumnName() {
...
}
Personally, I wouldn't worry about creating dependencies between unit tests. This sounds like a bit of a code smell to me. A few points:
