func DiffWithGolden ¶

func DiffWithGolden(t *testing.T, src []byte, golden string)

DiffWithGolden is a test helper that compares the src bytes with a file content whose path is provided in the 'golden' argument. If UpdateGolden flag is true, than the golden file is updated with the provided new content in 'src'.

func DisableLogging ¶

func DisableLogging() (reset func())

DisableLogging is a test helper that disable logging (in fact it sets its level to panic). It returns a function which when called, resets it to its previous level. Its useful to be called as follows in test/benchmarks:

func TestFoo(t *testing.T) {
    defer DisableLogging()()

    // logging is disabled for the whole test
}

func LessLogging ¶

func LessLogging() (reset func())

LessLogging is a test helper that decreases logging (in fact it sets its level to Error). It returns a function which when called, resets it to its previous level. Its useful to be called as follows in test/benchmarks:

func TestFoo(t *testing.T) {
    defer LessLogging()()

    // logging is set to Error for the whole test
}

func NewLogLineFromMap ¶

func NewLogLineFromMap(m map[baker.FieldIndex]string, sep byte) baker.Record

NewLogLineFromMap populates an baker.LogLine with the fields in m.

func TempDir ¶

func TempDir(tb testing.TB) (dir string, rmdir func())

TempDir is a test helper that creates a temporary directory, returns its name and a function which when called removes that directory. This is useful to be called as follows at the top of a test or benchmark requiring a temporary directory:

func TestFoo(t *testing.T) {
    dir, rmdir := testutil.TempDir(t)
    defer rmdir()

    // do something with dir
    ...
}

func TempFile ¶

func TempFile(tb testing.TB) (file string, rmfile func())

TempFile is a test helper that creates a temporary file, returns its name and a function which when called removes that file. This is useful to be called as follows at the top of a test or benchmark requiring a temporary file:

func TestFoo(t *testing.T) {
    name, rmfile := testutil.TempFile(t)
    defer rmfile()

    // do something with filename
    ...
}
