We write automation framework using TestNG and when we run it we get errors sometimes. So, it becomes important for us to know about error messages.
I have put some of the error messages that we get when we go wrong and execute TestNG XML file:
1.If two tests are having the same name then we see below error
at org.testng.TestNG.checkTestNames(TestNG.java:981)
at org.testng.TestNG.sanityCheck(TestNG.java:970)
at org.testng.TestNG.run(TestNG.java:1002)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:109)
2.If the testname doesnot enclosed in double quotes("") then we get below error
The value of attribute "name" associated with an element type "null" must not contain the '<' character.
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: The value of attribute "name" associated with an element type "null" must not contain the '<' character.

3.If the class name doesnt end with "/" character then we will see below error
org.testng.TestNGException: org.xml.sax.SAXParseException: The end-tag for element type "class" must end with a '>' delimiter.
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: The end-tag for element type "class" must end with a '>' delimiter.
4. If there is no space between parameter name and value fields then we will see below error
Ex :
org.testng.TestNGException: org.xml.sax.SAXParseException: Element type "parameter" must be followed by either attribute specifications, ">" or "/>".
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: Element type "parameter" must be followed by either attribute specifications, ">" or "/>".
5.If the parameter attribute doesnt end with "/" character then we will see below error
org.testng.TestNGException: org.xml.sax.SAXParseException: Element type "class" must be followed by either attribute specifications, ">" or "/>".
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: Element type "class" must be followed by either attribute specifications, ">" or "/>".
6. If the two parameters have the same name and value attributes then we will see below error
org.testng.TestNGException: org.xml.sax.SAXParseException: Element type "class" must be followed by either attribute specifications, ">" or "/>".
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: Element type "class" must be followed by either attribute specifications, ">" or "/>".
7.Make sure there are no spaces between "/" and ">".If there are any spaces then we will see below error.
org.testng.TestNGException: org.xml.sax.SAXParseException: Element type "class" must be followed by either attribute specifications, ">" or "/>".
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: Element type "class" must be followed by either attribute specifications, ">" or "/>".
