diff

对原项目进行了一点修改，只输出两个文本的差异部分。方便只关心差异部分的应用使用，比如网站监控。
Quick'n'easy string diffing functions for Golang based on github.com/sergi/go-diff. Mainly for diffing strings in tests.

See the docs on GoDoc.

Get it:

    ...
    `

    func TestFoo(t *testing.T) {
        actual := Foo(...)
        if a, e := strings.TrimSpace(actual), strings.TrimSpace(expected); a != e {
            t.Errorf("Result not as expected:\n%v", diff.LineDiff(e, a))
        }
    }
