listests#

List Go tests in packages with their subtests.

Usage#

# Has ./... as default.
listests

# Specific packages
listests ./some/package ./another/package


# With build tags
listests -tags=integration ./some/package

Example#

$ listests
TestSimple
TestSubTests
TestSubTests/t1
TestSubTests/t2
TestNestedSubTests
TestNestedSubTests/t1
TestNestedSubTests/t1/t1
TestSubTestsWithGeneratedNames
TestSubTestsWithGeneratedNames/<fmt.Sprintf("t%v", i)>
TestTable
TestTable/t1
TestTable/t2

Use --format to customize the output, see shell functions below as an example.

Misc#

Interactive with fzf + bat#

Might be more simpler but works for me.
