Deno.test

test

• test(t: TestDefinition): void

• test(fn: () => void | Promise<void>): void

• test(name: string, fn: () => void | Promise<void>): void

• • 定义在 lib.deno.ns.d.ts:59

  注册一个测试，它将在命令行执行 deno test 操作并且包含的模块看起来像一个测试模块时运行， 或者在使用 Deno.runTests 时显式运行。如果需要， fn 可以是异步的。

  Register a test which will be run when deno test is used on the command line and the containing module looks like a test module, or explicitly when Deno.runTests is used. fn can be async if required.

       import {assert, fail, assertEquals} from "https://deno.land/std/testing/asserts.ts";
  

       Deno.test({
         name: "example test",
         fn(): void {
           assertEquals("world", "world");
         },
       });
  

       Deno.test({
         name: "example ignored test",
         ignore: Deno.build.os === "win"
         fn(): void {
           // 仅在 Windows 机器上忽略这个测试。
         },
       });
  

       Deno.test({
         name: "example async test",
         async fn() {
           const decoder = new TextDecoder("utf-8");
           const data = await Deno.readFile("hello_world.txt");
           assertEquals(decoder.decode(data), "Hello world")
         }
       });
