[testng-users] How to load TestNG config within an executable JAR?

[TERACytE]

I have an shaded executable jar created by a Maven build. Within I have a
main class that executes and attempts to run a collection of TestNG tests.
It runs until it it attempts to load the xml config files for the tests.
The steps within the main class are:

suites.add("testng-A.xml");
suites.add("testng-B.xml");

testng.setTestSuites(suites);
testng.addListener(tla);
testng.run();

The problem is that I cannot get TestNG to successfully find the xml files.
I receive a "java.io.FileNotFoundException: testng-a.xml (No such file or
directory)" error. The location of the files in the JAR are:

/com/address/MyMainClass
/testng-a.xml
/testng-b.xml

I am running the jar with the following command:
java -jar uber.jar

Any ideas on how I can get this to work?

Hi,

TestNG expects these to be files, so I'm not surprised this is not working. We would need to change this part of the API so it can accept input streams instead, but I don't see an easy way to retrofit this in the XML classes at the moment.

As a workaround, you could extract these files from the jar file in a temporary location and pass the paths to these files to your XmlSuite objects...

Thank-you for the prompt reply. I was hopeful there was a way around this.
I tested my code with a hardcoded path outside of the JAR and it worked. I
now need to find a way to extract and reference them at runtime.

I was doing the exact same thing. But instead of extracting the file
from the jar, I used getResourceAsStream and then write the stream out
to file in the working folder and clean up the file after tests run.

//Retrieve the suite file from the jar and then write it out
to filesystem for use with testNG
InputStream is = pScanner.class.getResourceAsStream("/
testng.xml");
File mysuite = new File("testng.xml");
try {
OutputStream os = new FileOutputStream(mysuite);

byte buf[]=new byte[1024];
int len;
try {
while ((len=is.read(buf))>0) {
os.write(buf,0,len);
os.close();
is.close();
System.out.println(mysuite.toPath().toString());
}
} catch (IOException e) {
e.printStackTrace(); //To change body of catch
statement use File | Settings | File Templates.
}
} catch (FileNotFoundException e) {
e.printStackTrace(); //To change body of catch
statement use File | Settings | File Templates.
}

List<String> xmlFileList = new ArrayList();
xmlFileList.add("testng.xml");
TestListenerAdapter tla = new TestListenerAdapter();
TestNG testng = new TestNG();
testng.setTestClasses(new Class[] { pScanner.class });
testng.setTestSuites(xmlFileList);
testng.addListener(tla);
testng.run();

Hi,

May I know whether this is resolved and support is available in the latest version of Test NG. 

Or still I need to extract the XML outside and add it to the suites list. 

If the support is available, can some I get some code snippet, which I can refer to .

Regards,

Ashok

What happens when you try it using the latest released version of TestNG ?

I have tested jar exeution recently and it worked.

Thanks!

Hi,

I have tested it with below code snippet, and it worked. 

testngObj.setTestJar("Test.jar");

testngObj.setXmlPathInJar(this.testNgXmlFilePath);

testngObj.run();

This works only if the XML is a suite XML with Tests in it. 

I am actually trying to run a XML which has <suite-files> content. 

Example: 

Test_Suites.xml

<suite name="Suites Test" parallel="none">

<suite-files>

<suite-file path="Test1.xml"></suite-file>

<suite-file path="Test2.xml"></suite-file>

<suite-file path="Test3.xml"></suite-file>

</suite-files>

</suite>

I have a separate maven project (Test) having all the XMLs inside the resources folder which i build it as a JAR

Folder structure inside resources

resources 

            Test XMLs

                     Test_Suites.xml

                      Test1.xml

                      Test2.xml

                      Test3.xml

Any help towards this problem will be much appreciated. 

Regards,

Ashok

Ashok,

What version of TestNG are you using ? Please try using the latest released version viz ., 7.0.0-beta1. If it doesn't work please write up a bug and include a sample ( full fledged simple one ) that can be used to easily reproduce the problem.  

[Ashok Kumar]

Hi Krishnan,

I am using TesntNG Version 6.13.1.

BTW, did you try having the XMLs inside the JAR and tried to access it (as i have said in my previous post) directly, or you extracted the XMLs from the JAR locally and used local path reference. 

If it worked for you (accessing directly from the JAR), could you please share the code-snippet. 

The problem is I am getting an exception. I believe, Test NG picks up the XML in the JAR (main XML with sutite-files tag) set as part of the "testngObj.setXmlPathInJar(this.testNgXmlFilePath);" and it is not able to find the files given in the main XML file.

Ashok,

No I haven't tried. 

I remember some fixes went in around this functionality. That is why I am asking that you please try using TestNG 7.0.0-beta1. If it still doesn't work please write up a bug and we will try and get to it. 

[Ashok Kumar]

Hi Krishnan,

This worked on the new version "7.0.0-beta1"

Thanks.

Ashok

When I added jar feature to my project , I had to make sure all resources in my maven project are accessed as a resource stream. For example using getResourceAsStream instead InputStream or other File streams. Other than that I didn't have to do any significant changes. Hope this helps!

[amod mahajan]

Hi,

I am into the same problem. I have my testng.xml inside src/test/resources/xmlFiles/testng.xml and I have a runner class where I am calling this testng,xml. 

Locally it is running absolutely fine. 

But when I import it as an executable jar file which is generated inside target folder. Every path it is taking within /target. 

I have tried all getResourceAsStream() and whatever solution is discussed. 

TestNG Version - 7.3.0

I am using maven-assembly-plugin to export as a JAR. 

Java - 1.8

Thanks

Amod Mahajan

[Krishnan Mahadevan]

Can you please add some context behind your project, what your code looks like, what your runner looks like, what version of TestNG are you on, etc.,

 

Thanks & Regards

Hi amod,

you can see my issue "throw ”Cannot find class in classpath:*****.testclass” when execute test by jar mode", hope it can help you.
