How to print only the trace of custom exception? Instead TestNG Trace [duplicate]

This question already has answers here:
TestNG report with customized error in place of stack trace, when my script fails
(3 answers)
Closed 1 year ago.
class use extends Test {
#org.testng.annotations.Test
public void test() throws exc {
try {
System.out.println("test");
int a = 1 / 0;
System.out.println(a);
} catch (ArithmeticException e) {
throw new exc("This is EXC error");
}
}
class exc extends Exception {
private static final long serialVersionUID = 1L;
public exc(String a) {
super(a);
}
}
I want to print only 1st two lines in the console
Able to do that if I execute from Main Method, but using TestNG throws extra trace as shown.
This is the Console
FAILED: test
runner.exc: This is EXC error
at runner.use.test(Test.java:47)
I want to print upto here, but consoles shows the below too

You could use this code to get the first thwo lines as a string:
// tr is the exception object
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
tr.printStackTrace(pw); // Replace tr with your exception object
String[] stl = sw.toString().split("\n");
// Get the first two lines
// Use deleteCharAt(sb.length() - 1) to get rid of \r at the end of the line (You may not need to this)
StringBuilder sb = new StringBuilder();
if (stl.length > 0) sb.append(stl[0]).deleteCharAt(sb.length() - 1).append('\n');
if (stl.length > 1) sb.append(stl[1]).deleteCharAt(sb.length() - 1).append('\n');
// Use sb.toString() to get the result

Argument passed to verify() is of type Scanner and is not a mock

I'm trying to test that a Scanner object has been closed after being used in a try-with-resources. However I'm getting an error that says that my mocked Scanner is not a mock. I'm not sure what I'm doing wrong. This is the method that I'm trying to test:
private Collection<String> getCellIPs(String resultStoreHost, String path) throws IOException, PermissionsException {
Path tempDir = null;
Path cellFile = null;
List<String> results = new LinkedList<>();
try {
// Download the file.
SecureFTPClient ftpClient = new SecureFTPClient(resultStoreHost, "user", "password", true);
tempDir = Files.createTempDirectory(Paths.get("/store"), "celllist");
ftpClient.downloadFile(path + "/" + ResultStore.PARTITIONS_FILENAME, tempDir.toString());
cellFile = tempDir.resolve(ResultStore.PARTITIONS_FILENAME);
try (Scanner scanner = new Scanner(cellFile)) {
scanner.useDelimiter("\n");
while(scanner.hasNext()) {
String ip = scanner.next();
results.add(ip);
}
}
} finally {
try {
// Cleanup temporary files
if(cellFile != null) {
Files.delete(cellFile);
}
if (tempDir != null) {
Files.delete(tempDir);
}
} catch (IOException e) {
logger.warn("Couldn't delete temporary files in " + tempDir);
}
}
return results;
}
Here is my test class:
#RunWith(PowerMockRunner.class)
#PrepareForTest({DTDeliverQueryResultsJob.class, SecureFTPClient.class, Scanner.class})
public class DTDeliverQueryResultsJobTest
{
WorkflowRuntime mockWorkflowRuntime;
#Before
public void setUp() throws Exception {
mockWorkflowRuntime = PowerMockito.mock(WorkflowRuntime.class);
PowerMockito.whenNew(WorkflowRuntime.class).withAnyArguments().thenReturn(mockWorkflowRuntime);
}
#Test
public void testGetCellIPsWithNoException() throws Exception {
// Required mocks for DTDeliverQueryResultsJob
SecureFTPClient mockSecureFTPClient = PowerMockito.mock(SecureFTPClient.class);
PowerMockito.whenNew(SecureFTPClient.class).withAnyArguments().thenReturn(mockSecureFTPClient);
Scanner mockScanner = PowerMockito.mock(Scanner.class);
PowerMockito.when(mockScanner.hasNext()).thenReturn(false);
PowerMockito.whenNew(Scanner.class).withAnyArguments().thenReturn(mockScanner);
DTDeliverQueryResultsJob dtDeliverQueryResultsJob = PowerMockito.spy(new DTDeliverQueryResultsJob(mockWorkflowRuntime));
// Using Whitebox to call private method
Whitebox.invokeMethod(dtDeliverQueryResultsJob, "getCellIPs", Mockito.anyString(), Mockito.anyString());
// Verify that Scanner has been closed by try-with-resources
Mockito.verify(mockScanner).close();
}
}
And this is the error I'm getting:
log4j:WARN No appenders could be found for logger (dictionary.ZBaseLogsService).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Retry test case using TestNG while using ITestContext with test method

I am using dataprovider method and a test method (with ITestContext parameter in the test method). A simplified example is as follows :
#DataProvider(name="Dataprovider")
public Object[][] dataprovider(){
return new Object[][]{{1},{2,},{3}};
}
#Test(dataProvider="Dataprovider")
public void test(int data, ITestContext itx){
System.out.println(data);
org.testng.Assert.assertEquals(data, 3);
}
My Retry class and RetryListener classes are below :
public class RetryListener implements IAnnotationTransformer {
#Override
public void transform(ITestAnnotation testannotation, Class testClass,
Constructor testConstructor, Method testMethod) {
IRetryAnalyzer retry = testannotation.getRetryAnalyzer();
if (retry == null) {
testannotation.setRetryAnalyzer(Retry.class);
}
}
}
public class Retry implements IRetryAnalyzer {
private static int retryCount = 0;
private int maxRetryCount = 1;
// Below method returns 'true' if the test method has to be retried else 'false'
//and it takes the 'Result' as parameter of the test method that just ran
public boolean retry(ITestResult result) {
if (retryCount < maxRetryCount) {
System.out.println("Retrying test " + result.getName() + " with status "
+ getResultStatusName(result.getStatus()) + " for the " + (retryCount+1) + " time(s).");
retryCount++;
return true;
}
retryCount = 0;
return false;
}
public String getResultStatusName(int status) {
String resultName = null;
if(status==1)
resultName = "SUCCESS";
if(status==2)
resultName = "FAILURE";
if(status==3)
resultName = "SKIP";
return resultName;
}
}
Expected : When test fails, the retry is called by TestNG, then the dataprovider should return the same values to the test method.
Observed : Dataprovider returns the same value but test method doesn't run and the retry terminates and next test starts (new values will now be returned by dataprovider)
But my retry does not enter the test method ( It is not expecting the (int data, ITestContext itx) for test method). If I remove ITestContext, the retry works.
ITestContext is a must for maintaining the test case context. So how to perform retry along with keeping the ITestContext in the test method.

Within a #Test method that's powered by a data provider, I think its difficult to put the ITestContext as an explicit parameter and expect it to be injected by TestNG, because TestNG wouldn't know how to inject it (especially at which position).
Please see if the below would work for you (If you notice, I am now explicitly also passing in the ITestContext via the data provider )
import org.testng.IRetryAnalyzer;
import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class RetryWithDataProvider {
#DataProvider(name = "Dataprovider")
public Object[][] dataprovider(ITestContext ctx) {
return new Object[][]{{1, ctx}, {2, ctx}, {3, ctx}};
}
#Test(dataProvider = "Dataprovider", retryAnalyzer = Retry.class)
public void test(int data, ITestContext itx) {
System.out.println(data);
System.out.println("Current Test name is : " + itx.getName());
org.testng.Assert.assertEquals(data, 3);
}
public static class Retry implements IRetryAnalyzer {
private static int retryCount = 0;
private int maxRetryCount = 1;
public boolean retry(ITestResult result) {
if (retryCount < maxRetryCount) {
System.out.println("Retrying test " + result.getName() + " with status "
+ getResultStatusName(result.getStatus()) + " for the " + (retryCount + 1) + " time(s).");
retryCount++;
return true;
}
retryCount = 0;
return false;
}
String getResultStatusName(int status) {
String resultName = null;
if (status == 1)
resultName = "SUCCESS";
if (status == 2)
resultName = "FAILURE";
if (status == 3)
resultName = "SKIP";
return resultName;
}
}
}
Here's my console output

EasyMock unexpected method call

I can't work out how to setup the expectation of a call to a mock class. Here is the JUnit test:
public class AfkTest extends TestCase {
private AfkPlayerManager manager;
private Player player;
private Set<AfkPlayer> afkPlayers;
public void setUp() throws Exception {
super.setUp();
manager = new AfkPlayerManager();
player = EasyMock.createMock(Player.class);
afkPlayers = new HashSet<AfkPlayer>();
}
public void tearDown() {
}
public void testNotifyOfAfkPlayerSuccess() {
AfkPlayer afkPlayer = new AfkPlayer();
afkPlayer.setPlayer(player);
afkPlayer.setReason("TEST REASON");
afkPlayers.add(afkPlayer);
List<Player> onlinePlayers = new ArrayList<Player>();
onlinePlayers.add(player);
onlinePlayers.add(player);
EasyMock.expect(player.getDisplayName()).andReturn("TEST PLAYER");
player.sendMessage("§9TEST PLAYER§b is AFK. [TEST REASON]");
EasyMock.expectLastCall().times(1);
//activate the mock
EasyMock.replay(player);
assertTrue(manager.notifyOfAfkPlayer(onlinePlayers, afkPlayer));
//verify call to sendMessage is made or not
EasyMock.verify(player);
}
}
And the method that I am testing:
public class AfkPlayerManager implements Manager {
public boolean notifyOfAfkPlayer(Collection<Player> onlinePlayers, AfkPlayer afkPlayer) {
if (afkPlayer == null) {
return false;
}
String message = ChatColor.BLUE + afkPlayer.getPlayer().getDisplayName();
message += ChatColor.AQUA + " is AFK.";
if (afkPlayer.getReason().length() > 0) {
message += " [" + afkPlayer.getReason() + "]";
}
if (onlinePlayers != null && onlinePlayers.size() > 1) {
int notified = 0;
for (Player onlinePlayer : onlinePlayers) {
onlinePlayer.sendMessage(message);
notified++;
}
if (notified > 0) {
return true;
}
}
return false;
}
}
Why is this giving me the AssertionError:
java.lang.AssertionError: Unexpected method call

The expected and actual are different.
Expected: §9TEST PLAYER§b is AFK. [TEST REASON]
Actual: §9TEST PLAYER§b is AFK. [TEST REASON]
The  at the beginning is missing. So it fails as it should.

Why is my JSONObject related unit test failing?

I'm running my tests using gradle testFlavorType
JSONObject jsonObject1 = new JSONObject();
JSONObject jsonObject2 = new JSONObject();
jsonObject1.put("test", "test");
jsonObject2.put("test", "test");
assertEquals(jsonObject1.get("test"), jsonObject2.get("test"));
The above test succeeds.
jsonObject = new SlackMessageRequest(channel, message).buildBody();
String channelAssertion = jsonObject.getString(SlackMessageRequest.JSON_KEY_CHANNEL);
String messageAssertion = jsonObject.getString(SlackMessageRequest.JSON_KEY_TEXT);
assertEquals(channel, channelAssertion);
assertEquals(message, messageAssertion);
But the above two requests fail. The stack trace says that channelAssertion and messageAssertion are null, but not sure why. My question is: Why are the above two asserts failing?
Below is the SlackMessageRequest.
public class SlackMessageRequest
extends BaseRequest {
// region Variables
public static final String JSON_KEY_TEXT = "text";
public static final String JSON_KEY_CHANNEL = "channel";
private String mChannel;
private String mMessage;
// endregion
// region Constructors
public SlackMessageRequest(String channel, String message) {
mChannel = channel;
mMessage = message;
}
// endregion
// region Methods
#Override
public MethodType getMethodType() {
return MethodType.POST;
}
#Override
public JSONObject buildBody() throws JSONException {
JSONObject body = new JSONObject();
body.put(JSON_KEY_TEXT, getMessage());
body.put(JSON_KEY_CHANNEL, getChannel());
return body;
}
#Override
public String getUrl() {
return "http://localhost:1337";
}
public String getMessage() {
return mMessage;
}
public String getChannel() {
return mChannel;
}
// endregion
}

EDIT 5:55PM EST
I've figured out that I can log with System.out.println("") and then see the results by running gradle testFlavorType --debug and by trial and error I've discovered the following weird situation:
#Override
public JSONObject buildBody() throws JSONException {
System.out.println("buildBody mChannel = " + mChannel);
System.out.println("buildBody mMessage = " + mMessage);
JSONObject body = new JSONObject();
body.put(JSON_KEY_TEXT, getMessage());
body.put(JSON_KEY_CHANNEL, getChannel());
if (body.length() != 0) {
Iterator<String> keys = body.keys();
if (keys.hasNext()) {
do {
String key = keys.next();
System.out.println("keys: " + key);
} while (keys.hasNext());
}
} else {
System.out.println("There are no keys????");
}
return body;
}
For some reason, "There are no keys????" is printing out?!?!?!?! Why?!
EDIT 6:20PM EST
I've figured out how to debug unit tests. According to the debugger, the assigned JSONObject is returning "null". I have no clue what this means (see below). Since I think this is relevant, my gradle file includes the following:
testOptions {
unitTests.returnDefaultValues = true
}
It's especially strange because if I construct a JSONObject inside the test, then everything works fine. But if it is part of the original application's code, then it doesn't work and does the above.

As Lucas says, JSON is bundled up with the Android SDK, so you are working with a stub.
The current solution is to pull JSON from Maven Central like this:
dependencies {
...
testImplementation 'org.json:json:20210307'
}
You can replace the version 20210307 with the the latest one depending on the Android API. It is not known which version of the maven artefact corresponds exactly/most closely to what ships with Android.
Alternatively, you can download and include the jar:
dependencies {
...
testImplementation files('libs/json.jar')
}
Note that you also need to use Android Studio 1.1 or higher and at least build tools version 22.0.0 or above for this to work.

The class JSONObject is part of the android SDK. That means that is not available for unit testing by default.
From http://tools.android.com/tech-docs/unit-testing-support
The android.jar file that is used to run unit tests does not contain
any actual code - that is provided by the Android system image on real
devices. Instead, all methods throw exceptions (by default). This is
to make sure your unit tests only test your code and do not depend on
any particular behaviour of the Android platform (that you have not
explicitly mocked e.g. using Mockito).
When you set the test options to
testOptions {
unitTests.returnDefaultValues = true
}
you are fixing the "Method ... not mocked." problem, but the outcome is that when your code uses new JSONObject() you are not using the real method, you are using a mock method that doesn't do anything, it just returns a default value. That's the reason the object is null.
You can find different ways of solving the problem in this question: Android methods are not mocked when using Mockito

Well, my first hunch would be that your getMessage() method returns null. You could show the body of that method in your question and have us find the answer for you, but you should probably research how to debug android applications using breakpoints.
That way you can run your code step by step and see the values of each variable at every step. That would show you your problem in no time, and it's a skill you should definitely master as soon as possible if you intend to get seriously involved in programming.
