Deno test Leaking resources

Hi i currently try to get used to deno.test but Deno.readTextFile makes the test end in the following error:

error: Leaking resources:
  - A file (rid 3) was opened during the test, but not closed during the test. Close the file handle by calling `file.close()`.

error: Leaking resources:
  - A file (rid 3) was opened during the test, but not closed during the test. Close the file handle by calling `file.close()`.

My function looks like this:

export async function test() {
    try {
        const test = await Deno.readTextFile("./test.txt");
        return true
    }
    catch (err) {
        log(err);
        return false;
    }
}

export async function test() {
    try {
        const test = await Deno.readTextFile("./test.txt");
        return true
    }
    catch (err) {
        log(err);
        return false;
    }
}

Is there a way to close the file so that i don't get the error ?

How to transform a Readable Stream to a file.

I have a ReadableStream from a post request and i cant find a way to transform the body(ReadableStream) to a file. I tried to pipe the ReadableStream into a file like this const file = await Deno.open('./test.png', {create: true,write: true,}) myPostRequest.body.pipeTo(file.writable); file.close(); I always get: error: Uncaught (in promise) BadResource: Bad resource ID at async write (deno:ext/net/01_net.js:33:12) at async Object.write (deno:ext/net/01_net.js:82:25) what is the correct way to create a file from a readable stream ?
