For example:
Deno.test({
name: "Testing qr-html generation",
fn: async () => {
await createQRhtml();
assertEquals(exists("out/qr.html"), true);
}
});
createQRhtml() function takes arguments from command line. Specifically, first argument: Deno.args[0].
How to specify here?
You can pass your CLI arguments after a double dash (--) like this:
deno test args.test.ts -- hello
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:
deno help COMMAND_NAME
This is included in the output of deno help test:
USAGE:
deno test [OPTIONS] [files]... [-- <SCRIPT_ARG>...]
