expecto

example spec

Idea is to provide simple wrapper for testing library that immediately exits when assertion fails and prints colored output with diff.

Most matchers follow the pattern: matcher(t *testing.T, msg string, value any, expected any)

Matchers

expecto.NoErr(t, "parsing config", err)
expecto.Eq(t, "number of files", len(c.Files), 1)
expecto.Eq(t, "number of chunks", len(c.Files[0].Chunks), 2)
expecto.Eq(t, "number of migrations", len(c.Files[0].Migrations), 1)
expecto.Nil(t, "transaction", c.Transaction)
expecto.Contains(t, "notification message", str, "error message")
expecto.Map(t, anyMap).HasKey("has cache key", "cache-1")

See files for the full list of assertions.

Temporary file system

Random dir in system TempDir is created.

fs, dir, cleanup := expecto.TempFS(
   "src/path.txt",
   "content1",
   "src/b/2.txt",
   "content2,
)
defer cleanup()
