Skip Pending Tests in ExUnit

In ExUnit you have the ability to tag a test with any atom:

@tag :awesome
test "my awesome test" do
end

@tag :terrible
test "my terrible test" do
end

And then you can exclude those tags at the command line so that your terrible test does not run:

mix test --exclude terrible

So you can make your own tag :pending and exclude those. If you donโ€™t want to have to set the flag at the command line everytime, you can call ExUnit.configure. This is typically placed in the test/test_helper.exs file before ExUnit.start().

ExUnit.configure(exclude: :pending)
ExUnit.start()

Now your pending tests will not run.

That is how you can use custom tags to skip tests, but you can also just use the built in skip tag to skip tests.

@tag :skip
test "my terrible test" do
end
