[英]How to pass command line arguments in deno test?
For example:例如:
Deno.test({
name: "Testing qr-html generation",
fn: async () => {
await createQRhtml();
assertEquals(exists("out/qr.html"), true);
}
});
createQRhtml()
function takes arguments from command line. createQRhtml()
function 从命令行获取 arguments。 Specifically, first argument: Deno.args[0]
.具体来说,第一个参数:
Deno.args[0]
。
How to specify here?这里如何指定?
You can pass your CLI arguments after a double dash ( --
) like this:您可以在双破折号 (
--
) 之后传递 CLI arguments,如下所示:
deno test args.test.ts -- hello
args.test.ts
: args.test.ts
:
import {assert} from 'https://deno.land/std@0.109.0/testing/asserts.ts';
function isHello (str?: unknown): boolean {
return str === 'hello';
}
Deno.test('First CLI argument is "hello"', () => {
const [firstArg] = Deno.args;
assert(isHello(firstArg));
});
You can learn about the test
commmand and other commands in your CLI using the form:您可以使用以下形式了解 CLI 中的
test
命令和其他命令:
deno help COMMAND_NAME
This is included in the output of deno help test
:这包含在
deno help test
的 output 中:
USAGE:
deno test [OPTIONS] [files]... [-- <SCRIPT_ARG>...]
