Not quite sure if this is a bug but it's annoying: If the example tested string contains a trailing space before a newline, the test always fails no matter how. // this test passes func ExampleFormat() { fmt.Println("a\nb") // Output: // a // b } // this test fails no matter we put "a" or "a " in the first output line. func ExampleFormat() { fmt.Println("a \nb") // Output: // a // b }
The doc <https://pkg.go.dev/testing#hdr-Examples> says "The comparison ignores leading and trailing space." I guess what's going on here is that it cut the trailing space in the desired output, but doesn't handle the space in the practical output if it's before a newline. Because the practical output may come from a 3rd party library, we have to respect how they print things. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
