cmd/go: print test2json start events

2022-11-09T17:33:07Z

Add a new "Action":"start" test2json event to mark the start of the test binary execution. This adds useful information to the JSON traces, and it also lets programs watching test execution see the order in which the tests are being run, because we arrange for the starts to happen sequentially.

cmd/go: make go test -json report failures for panicking/exiting tests

2020-03-06T17:28:04Z

'go test -json' should report that a test failed if the test binary did not exit normally with status 0. This covers panics, non-zero exits, and abnormal terminations. These tests don't print a final result when run with -test.v (which is used by 'go test -json'). The final result should be "PASS" or "FAIL" on a line by itself. 'go test' prints "FAIL" in this case, but includes error information. test2json was changed in CL 192104 to report that a test passed if it does not report a final status. This caused 'go test -json' to report that a test passed after a panic or non-zero exit. With this change, test2json treats "FAIL" with error information the same as "FAIL" on a line by itself. This is intended to be a minimal fix for backporting, but it will likely be replaced by a complete solution for #29062.

testing: provide additional information when test funcs panic

2019-10-30T20:46:44Z

Flush the output log up to the root when a test panics. Prior to this change, only the current test's output log was flushed to its parent, resulting in no output when a subtest panics. For the following test function: func Test(t *testing.T) { for i, test := range []int{1, 0, 2} { t.Run(fmt.Sprintf("%v/%v", i, test), func(t *testing.T) { _ = 1 / test }) } } Output before this change: panic: runtime error: integer divide by zero [recovered] panic: runtime error: integer divide by zero (stack trace follows) Output after this change: --- FAIL: Test (0.00s) --- FAIL: Test/1/0 (0.00s) panic: runtime error: integer divide by zero [recovered] (stack trace follows) Fixes #32121 Change-Id: Ifee07ccc005f0493a902190a8be734943123b6b7 Reviewed-on: https://go-review.googlesource.com/c/go/+/179599 Run-TryBot: Damien Neil TryBot-Result: Gobot Gobot Reviewed-by: Ian Lance Taylor
