Usage
Usage: gott [flags]
Parses go test verbose output and produces a list of tests sorted by how time consuming they are.
gott flags:
-c omit entries that take less than this much time (0s)
-p pass through go test output (false)
Parallel Children
go test reports how long a test function takes to return. Test functions don't wait on their
parallel children, so it can be difficult to answer the question "How long did this test and
all of its children take?".
In gott,
The first column of durations show how long the test functions took to return.
The second column shows long it took for all children to return.
Ranking Algorithm
gott orders outputted tests by max(testTook, childrenTook).
The longest test cases are at the bottom to reduce scrolling.
