Describe the bug && Reproduction I’m experiencing the same issue outlined in #4119.

Run tns test android with usesCleartextTraffic=false, the test app shows “no reachable hosts”. Setting usesCleartextTraffic=true allows the tests to execute.

I don’t want to set usesCleartextTraffic to true with my production application, so I’m wondering how I get around this.

Expected behavior I expect the tests to run 😄

Additional context This was supposed to be resolved with this pull request. I see that there is an AndroidManifest.xml file in those changes, and I’m wondering if that is supposed to override the settings in my application’s manifest https://github.com/NativeScript/nativescript-unit-test-runner/pull/30

@jevenson , the idea is to include a script on your side that sets usesCleartextTraffic to true and then runs the tests, for example in Node.js script you can do something like:

const path = require("path");
const fs = require("fs");
const childProcess = require("child_process");
const os = require("os");
const pathToAndroidManifestInAppResources = path.join(__dirname, "app", "App_Resources", "Android", "src", "main", "AndroidManifest.xml");

const currentContent = fs.readFileSync(pathToAndroidManifestInAppResources).toString();
const newContent = currentContent.replace('android:usesCleartextTraffic="false"', 'android:usesCleartextTraffic="true"');
fs.writeFileSync(pathToAndroidManifestInAppResources, newContent);

const tnsExecutable = os.platform() === "win32" ? "tns.cmd" : "tns";
try {
    const result = childProcess.spawnSync(tnsExecutable, ["test", "android", "--justlaunch"], { stdio: "inherit" });
    console.log(result);
} finally {
    fs.writeFileSync(pathToAndroidManifestInAppResources, currentContent);
}

Currently it is not possible to run the test on API level 28 or above without this setting and we do not have plans to research other ways to achieve this.
