Android TestRunner fails due to IllegalState exception

Question

I am running android Instrumentation tests to unit test activity and specifically if the WebView has loaded or not code is as follows, but each time i get exception

Running tests Test running started Test failed to run to completion. Reason: 'Instrumentation run failed due to 'java.lang.IllegalStateException''. Check device logcat for details Test running failed: Instrumentation run failed due to 'java.lang.IllegalStateException'

There are no Logcat logs , just this message in console , tried on Genymotion as well as device both are on android 5.0.

Code is as follows

public class WebViewActivityTest extends ActivityInstrumentationTestCase2 <WebViewActivity> {

    WebView webView;
    WebViewActivity testActivity;

    public WebViewActivityTest()
    {
        super(WebViewActivity.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        testActivity = getActivity();

    }

    public void testWebView()
    {
        webView = (WebView)testActivity.findViewById(R.id.webView);
        assertNotNull(webView);
    }

    public void testPreconditions() {

        assertNotNull("Webview activity is null",testActivity);
    }
}

I have tried searching but got no clue why this exception is occurring , please help.

Answer 1

Add a catch statment after the try stetment and give the try statment an exeption. the syntext might be a little off but that should fix your probleme

public class WebViewActivityTest extends ActivityInstrumentationTestCase2 <WebViewActivity> {

WebView webView;
WebViewActivity testActivity;

public WebViewActivityTest()
{
    super(WebViewActivity.class);
}

@Override
protected void setUp() throws(exeption e) {
    super.setUp();
    testActivity = getActivity();
    catch(exeption e)
    System.out.println("Nope!);

}

public void testWebView()
{
    webView = (WebView)testActivity.findViewById(R.id.webView);
    assertNotNull(webView);
}

public void testPreconditions() {

    assertNotNull("Webview activity is null",testActivity);
}

}
