JUnit Test throwing ClassNotFoundExcpetion while execution - java

I'm trying to write a simple Appium test for android app using Junit in Eclipse. The below is my code.
#Test
public void test() throws MalformedURLException{
AndroidDriver<MobileElement> driver;
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android Emulator");
cap.setCapability(MobileCapabilityType.APP, "C:\\Automation\\ExpediaHotelsFlightsCarsv6.10.0.apk");
cap.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.APPIUM);
cap.setCapability(MobileCapabilityType.PLATFORM_NAME, Platform.ANDROID);
***driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"),cap);***
driver.launchApp();
}
I'm getting the below error while running the test at the line
driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"),cap);

Please help me fix this and understand the solution.

Please ensure you have added all dependency for selenium in your pom or build path. You must have below jar in your pom,
selenium-server-standalone-XXX.jar
selenium-java-XXX.jar.

Unable to access test resources

I have a file testPristineCopy.xlsx in ..\src\test\resources folder. In my unit test< i try and access it like this:
InputStream testInputStream = this.getClass().getResourceAsStream("/testPristineCopy.xlsx");
I get an error for this line when I tried running the unit test using JUnit. The stack trace is below:

Any idea what the problem is? I need these resources to be accessible for the test cases when they are run on Jenkins.

You can use the relative path to access any resource file under src/test/resources folder. Something like this.
InputStream testInputStream = new FileInputStream(new File("src/test/resources/testPristineCopy.xlsx"));

Cannot run JUnit-test in eclipse but with gradle

I have a gradle project in eclipse (Version: Neon.3 Release (4.6.3)
Build id: 20170314-1500). When i execute my simple JUnit-test with gradle, everything works fine. But if i execute/debug the test in eclipse (by the context
menu), the test crashes.
The exception: java.lang.NoClassDefFoundError. I think the jasperreports dependency causes the crashes with a wrong CLASSPATH (?). Or the combination of gradle and eclipse does not work correctly.
Any help would be greatly appreciated:)
I have reduce the project to a minimum.

Getting ExceptioninitializerError in JUnit

Below is the error which i am getting while running JUnit test case.
While running JUnit test case for SV as code, I am getting the below error, even though all the SV as Code jars. the code is for create virtual services. In case i remove the line "forGet(URL)......;" the test case would pass, else it throws an error.

Pls suggest.

One of the SV jars, has a dependency on JDK1.8 jar(tools.jar), so we need to add JDK1.8 library in buildpath of the project.

As the exception clearly states, you have to provide the path to the chrome driver executable. This can be set in your java code System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver") or it cant be passed at the command line -Dwebdriver.chrome.driver=/path/to/chromedriver

I found a solution - https://github.com/kaeawc/testable-active-android/blob/master/app/src/test/java/io/kaeawc/activeandroidapp/model/ActiveAndroidModelSpec.java
But the fact is that in addition I need PowerMockRunner and RobolectricGradleTestRunner. The project uses the class Application (it is stored on the Component Dagger). Options from here did not help.
In the first case:
#RunWith(RobolectricGradleTestRunner.class)
#Config(constants = BuildConfig.class, manifest = "src/test/TestManifest.xml", sdk = Build.VERSION_CODES.LOLLIPOP)
#PowerMockIgnore({"org.mockito.*", "org.robolectric.*", "android.*"})
#PrepareForTest({ Cache.class, TableInfo.class, Context.class, ContentResolver.class, ContentProvider.class, ContentValues.class })
#SuppressStaticInitializationFor("com.activeandroid.content.ContentProvider")
public class BaseTest {
#Rule
public PowerMockRule rule = new PowerMockRule();
#Test
public void setup() throws Exception {
PowerMockito.mockStatic(ContentProvider.class);
PowerMockito.when(ContentProvider.createUri(Model.class, 0l)).thenReturn(null);
assertTrue(ContentProvider.createUri(null, null) == null);
}
}

What should I do?

For the exception "org.powermock.api.mockito.ClassNotPreparedException: "
You could try to put this annotation on top of the class declaration or test method.
#RunWith(PowerMockRunner.class)
#PrepareForTest(CommPortIdentifier.class)
All the best,
