Tests use the signature "XTest(t TestingT)". Since runtime can't import // testing, test functions can't use testing.T, so instead we have the T // interface, which *testing.T satisfies. And we start names with "XTest" // because otherwise go test will complain about Test functions with the wrong // signature. To actually expose these as test functions, this file contains // trivial wrappers. // // 2. Runtime package tests can't directly import other std packages, so we // inject any necessary functions from std. // TODO: Generate this package runtime_test import ( "fmt" "internal/testenv" "runtime" "testing" ) func init() { runtime.FmtSprintf = fmt.Sprintf runtime.TestenvOptimizationOff = testenv.OptimizationOff } func TestInlineUnwinder(t *testing.T) { runtime.XTestInlineUnwinder(t) } func TestSPWrite(t *testing.T) { runtime.XTestSPWrite(t) }
