d命名单元测试

​​原文​​

通常在独立​​单元测试​​​上工作,因为​​速度​​​和​​更少输出​​​,只想​​运行​​​一个.而通常在文件中有几个​​单元测试​​​.急需要​​命名​​​单元测试.
只需要,​​​version(newFeature) unittest {}​​.

#! /usr/bin/env dub
/++ dub.sdl:

int factorial(int n) => n <= 1 ? 1 : n * factorial(n - 1);

@("!5") unittest {
    assert(factorial(5) == 120);
}

@("!0 and !1") unittest {
    assert(factorial(0) == 1);
    assert(factorial(1) == 1);
}

version (unittest) {
} else {
    void main(string[] args) {
        import std.conv :;
        import std.stdio :;

        writeln(args[1].to!int.factorial);
    }
}
//用法:

$ ./fact.d 10
3628800
$ dub -q test --single fact.d
 ? fact !5
 ? fact !0 and !1

Summary: 2 passed, 0 failed in 0
