JUnit tests pass in Eclipse but fail in Maven Surefire

Question

I have written some JUnit tests using JUnit 4 and spring-test libraries  When I run the tests inside Eclipse then run fine and pass  But when I run them using Maven  during the build process   they fail giving a spring related error  I am not sure what is causing the problem  JUnit  Surefire or Spring  Here is my test code  spring configuration and the exception that I get from Maven

I had the same problem  JUnit tests failed in Maven Surefire but passed in Eclipse  and managed to solve it by setting forkMode to always in the maven surefire configuration in pom xml     lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-surefire-plugin lt  artifactId gt       lt version gt 2 12 lt  version gt       lt configuration gt           lt forkMode gt always lt  forkMode gt       lt  configuration gt   lt  plugin gt    Surefire parameters  http   maven apache org plugins maven-surefire-plugin test-mojo html  Edit  January 2014    As Peter Perh  c pointed out  the forkMode parameter is deprecated since Surefire 2 14  Beginning from Surefire 2 14 use this instead    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-surefire-plugin lt  artifactId gt       lt version gt 2 16 lt  version gt       lt configuration gt           lt reuseForks gt false lt  reuseForks gt           lt forkCount gt 1 lt  forkCount gt       lt  configuration gt   lt  plugin gt    For more information see Fork Options and Parallel Test Execution

In my case the reason was a bug in the code  The test relied on a certain order of elements in a HashSet  which turned out to be different when run either in Eclipse or in Maven Surefire

I had this problem today testing a method that converted an object that contained a Map to a JSON string  I assume Eclipse and the Maven surefire plugin were using different JREs which had different implementations of HashMap ordering or something  which caused the tests run through Eclipse to pass and the tests run through surefire to fail  assertEquals failed   The easiest solution was to use an implementation of Map that had reliable ordering

I had the same issue  but the problem for me was that Java assertions  e g  assert num   0   were not enabled for Eclipse  but were enabled when running maven   Therefore running the jUnit tests from Eclipse did not catch trigger the assertion error   This is made clear when using jUnit 4 11  as opposed to the older version I was using  because it prints out the assertion error  e g   java lang AssertionError  null     at com company sdk components schema views impl InputViewHandler  lt init gt  InputViewHandler java 26      at test com company sdk util TestSchemaExtractor MockInputViewHandler  lt init gt  TestSchemaExtractor java 31      at test com company sdk util TestSchemaExtractor testCreateViewToFieldsMap TestSchemaExtractor java 48

I suddenly experienced this error  and the solution for me was to disable to run tests in parallel  Your milage may vary  since I could lower number of failing tests by configuring surefire to run parallel tests by   classes                  lt plugin gt                   lt artifactId gt maven-surefire-plugin lt  artifactId gt                   lt version gt 2 22 2 lt  version gt                   lt configuration gt                       lt parallel gt classes lt  parallel gt                       lt threadCount gt 10 lt  threadCount gt                   lt  configuration gt               lt  plugin gt   As I wrote first  this was not enough for my test suite  so I completely disabled parallel by removing the  lt configuration gt  section

Usually when tests pass in eclipse and fail with maven it is a classpath issue because it is the main difference between the two   So you can check the classpath with maven -X test and check the classpath of eclipse via the menus or in the  classpath file in the root of your project   Are you sure for example that personservice-test xml is in the classpath

This has helped me in troubleshooting my problem  I had a similar symptoms in that maven would fail however running junit tests runs fine   As it turns out my parent pom xml contains the following definition        lt plugin gt         lt artifactId gt maven-surefire-plugin lt  artifactId gt         lt version gt 2 9 lt  version gt         lt configuration gt           lt forkMode gt pertest lt  forkMode gt           lt argLine gt -Xverify none lt  argLine gt         lt  configuration gt       lt  plugin gt    And in my project I override it to remove the argLine        lt plugin gt          lt artifactId gt maven-surefire-plugin lt  artifactId gt          lt configuration gt               lt forkMode gt pertest lt  forkMode gt               lt argLine combine self  override  gt  lt  argLine gt             lt  configuration gt       lt  plugin gt    Hopefully this will help someone in troubleshooting surefire plugin

This doesn t exactly apply to your situation  but I had the same thing -- tests that would pass in Eclipse failed when the test goal from Maven was run   It turned out to be a test earlier in my suite  in a different package   This took me a week to solve   An earlier test was testing some Logback classes  and created a Logback context from a config file   The later test was testing a subclass of Spring s SimpleRestTemplate  and somehow  the earlier Logback context was held  with DEBUG on   This caused extra calls to be made in RestTemplate to log HttpStatus  etc   It s another thing to check if one ever gets into this situation  I fixed my problem by injecting some Mocks into my Logback test class  so that no real Logback contexts were created

I had the same problem  and the solution for me was to allow Maven to handle all dependencies  including to local jars  I used Maven for online dependencies  and configured build path manually for local dependencies  Thus  Maven was not aware of the dependencies I configured manually   I used this solution to install the local jar dependencies into Maven   How to add local jar files in maven project

Test execution result different from JUnit run and from maven install seems to be symptom for several problems   Disabling thread reusing test execution did also get rid of the symptom in our case  but the impression that the code was not thread-safe was still strong   In our case the difference was due to the presence of a bean that modified the test behaviour  Running just the JUnit test would result fine  but running the project install target would result in a failed test case  Since it was the test case under development  it was immediately suspicious   It resulted that another test case was instantiating a bean through Spring that would survive until the execution of the new test case  The bean presence was modifying the behaviour of some classes and producing the failed result   The solution in our case was getting rid of the bean  which was not needed in the first place  yet another prize from the copy paste gun    I suggest everybody with this symptom to investigate what the root cause is  Disabling thread reuse in test execution might only hide it

You don t need to inject a DataSource in the JpaTransactionManager since the EntityManagerFactory already has a datasource  Try the following    lt bean id  transactionManager  class  org springframework orm jpa JpaTransactionManager  gt      lt property name  entityManagerFactory  ref  entityManagerFactory    gt   lt  bean gt

I had a similar problem  I ran my tests disabling the reuse of forks like this mvn clean test -DreuseForks false  and the problem disappeared  The downside is that the overall test execution time will be longer  that s why you may want to do this from the command line only if necessary

I had a similar problem with a different cause and therefore different solution   In my case  I actually had an error where a singleton object was having a member variable modified in a non-threadsafe way   In this case  following the accepted answers and circumventing the parallel testing would only hide the error that was actually revealed by the test   My solution  of course  is to fix the design so that I don t have this bad behavior in my code

I am not sure that this is an answer to the original question  since the stacktrace here looks slightly different  but it may be useful to others    You can get tests failing in Surefire when you are also running Cobertura  to get code coverage reports    This is because Cobertura requires proxies  to measure code use  and there is some kind of conflict between those and Spring proxies   This only occurs when Spring uses cglib2  which would be the case if  for example  you have proxy-target-class  true   or if you have an object that is being proxied that does not implement interfaces   The normal fix to this is to add an interface   So  for example  DAOs should be interfaces  implemented by a DAOImpl class   If you autowire on the interface  everything will work fine  because cglib2 is no longer required  a simpler JDK proxy to the interface can be used instead and Cobertura works fine with this    However  you cannot use interfaces with annotated controllers  you will get a runtime error when trying to use the controller in a servlet  - I do not have a solution for Cobertura   Spring tests that autowire controllers

It is most likely that your configuration files are in src main resources  while they must be under src test resources to work properly under maven   https   cwiki apache org UIMA differences-between-running-unit-tests-in-eclipse-and-in-maven html  I m replying this after two years  cause I couldn t find this answer here and I think it is the right one
