Can I run a single test in a suite?

Question

I have setup a test suite for my struct (https://github.com/stretchr/testify#suite-package). Before I was able to run a single test by specifying just a pattern:

go test -v ./services/gateways/... -run mytest

This approach doesn't work after conversion. Bad luck or is there a way?

Does `-m` do what you expect? From the documentation: `Regular expression to select the methods of test suites specified command-line argument "-m"` maybe combined with `-run` to specify the suite? — JimB, Nov 05 '16 at 01:18
According to help, "`run` is to - Run only those tests and examples matching the regular expression." The content of the file only has one test that calls the suite method. So `go test` after analyzing files may just not find matches if it looks for something like `func TestBlah(t *testing.T)`... — Schultz9999, Nov 05 '16 at 05:25
yes, `-run` picks the `Test*` function to run, which starts a particular suite, and the `-m` flag will filter which suite methods to execute. — JimB, Nov 06 '16 at 14:59

You can run single methods by specifying the -testify.m argument.

to run this suite method the command is:

go test -v github.com/vektra/mockery/mockery -run ^TestGeneratorSuite$ -testify.m TestGenerator

Now the flag has been changed to -m (go version go1.9) – Alberto Megía Oct 16 '17 at 21:19
It's a shame that you can't just mark a test with .only or something like you can do in other test frameworks. – Landon Poch Mar 02 '18 at 22:58

i think you're SOL with that package but here's a similar approach with go 1.7's stock testing tools:

package main

import "testing"

func TestSuite1(t *testing.T) {
    t.Run("first test", func(t *testing.T) { t.Fail() })
    t.Run("second test", func(t *testing.T) { t.Fail() })
}

func TestSuite2(t *testing.T) {
    t.Run("third test", func(t *testing.T) { t.Fatal("3") })
    t.Run("fourth test", func(t *testing.T) { t.Fatal("4") })
}

Example output for one suite:

 therealplato/stack-suites Ω go test -run TestSuite1       
--- FAIL: TestSuite1 (0.00s)
    --- FAIL: TestSuite1/first_test (0.00s)
    --- FAIL: TestSuite1/second_test (0.00s)
FAIL
exit status 1
FAIL    github.com/therealplato/stack-suites    0.005s

Example output for one test:

 therealplato/stack-suites Ω go test -run TestSuite2/third 
--- FAIL: TestSuite2 (0.00s)
    --- FAIL: TestSuite2/third_test (0.00s)
        main_test.go:11: 3
FAIL
exit status 1
FAIL    github.com/therealplato/stack-suites    0.005s

Interesting. Perhaps `TestSuite2/third` is the key. I'll try. Thank you! — Schultz9999, Nov 08 '16 at 01:11

Can I run a single test in a suite?
