How to verify the toast message via appium with uiautomator2?

Question

I have write one app which include one button and it will show one toast message.

public void onClickShowToast(View view) {
    Toast.makeText(getBaseContext(), "Change port successfully", Toast.LENGTH_LONG).show();
}

And then, i write one test case with appium try to verify it.

//APPIUM Version: 1.6.3;
//JAVA: 1.8;
//JAVA Client: 5.0.0;
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);

driver.findElementByXPath("//*[contains(@text,'Button')]").click();
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//*[contains(@text, 'port')]")))

But, the result is fail:

org.openqa.selenium.TimeoutException: Expected condition failed: waiting for presence of element located by: By.xpath: //*contains(@text, 'port')

Answer 1

The trick is finding the right XPath . I managed this using one of the following:

//android.widget.Toast
//android.widget.Toast[@text='toast text']

Answer 2

You can capture the toast like this:

WebElement toastView = androidDriver.findElement(By.xpath("//android.widget.Toast[1]")); String text = toastView.getAttribute("name");

Here is my solution.
