How do I test Expo application without building apk with appium? - react-native

Question

I try to make some tests on my Expo application but I can't launch it with appium,
Here is my capabilities:
const capabilities = {
platformName: 'android',
deviceName: 'Emulator1',
automationName: 'UiAutomator2',
pkg: 'host.exp.exponent',
intentAction: 'android.intent.action.VIEW',
activity: 'host.exp.exponent.experience.HomeActivity',
appWaitForLaunch: true,
path: '/wd/',
port: 4723,
};
I got this :
ERROR webdriver: Request failed with status 404 due to unknown command: The requested resource could not be found, or a request was received using an HTTP method that is not supported by the mapped resource

If you are using "webdriverio": "^7.0.7" package: try updating your configuration file like this :
wdio.conf.js
exports.config = {
services: ['appium'],
port: 4723,
path: '/wd/hub/',
hostname: 'localhost',
protocol: 'http',
specs: [
'./test/specs/**/*.js',
],
maxInstances: 1,
capabilities: [{
platformName: 'android',
deviceName: 'test', // Change to the name of the AVD you're using
automationName: 'UiAutomator2',
appPackage: 'host.exp.exponent',
appActivity: 'host.exp.exponent.experience.HomeActivity',
appWaitActivity: 'host.exp.exponent.experience.HomeActivity',
intentAction: 'android.intent.action.MAIN',
appWaitForLaunch: true,
newCommandTimeout: 180,
uiautomator2ServerInstallTimeout: 100000,
adbExecTimeout: 1000000,
skipLogcatCapture: true,
}],
logLevel: 'trace',
bail: 0,
waitforTimeout: 10000,
connectionRetryTimeout: 1200000,
connectionRetryCount: 3,
framework: 'mocha',
reporters: ['spec'],
mochaOpts: {
ui: 'bdd',
timeout: 180000,
},
};
path port are not in capabilities array.
