-------------------------------------------
Summary: NPE in
org.apache.maven.plugin.surefire.report.AbstractTextReporter
Key: SUREFIRE-848
URL: https://jira.codehaus.org/browse/SUREFIRE-848
Project: Maven Surefire
Issue Type: Bug
Components: Junit 4.x support, Maven Surefire Plugin
Affects Versions: 2.12
Reporter: Stephan Schroevers
Attachments: example.tbz
The combination Surefire/JUnit 4 causes a {{NullPointerException}} in
{{org.apache.maven.plugin.surefire.report.AbstractTextReporter}} if one has a
{{RunListener}} configured which (for whatever reason) throws an exception in
its {{#testRunStarted(Description)}} method.
I have [attached|^example.tbz] a dummy project; run {{`mvn test`}} to see the
problem. The cause of this issue is that {{AbstractTextReporter}} initializes
its {{testResults}} field when
{{AbstractTextReporter#testSetStarting(ReportEntry)}} is called, which (it
seems) doesn't happen until JUnit invokes
{{RunNotifier#fireTestStarted(Description)}}. This is too late, because an
exception during the invocation of
{{RunNotifier#fireTestRunStarted(Description)}} causes
{{AbstractTextReporter#testError(ReportEntry, String, String)}} to be invoked.
The result is an NPE on line 103.

Note that this issue seems to have been the root cause of SUREFIRE-157; the
[last
comment|jira.codehaus.org/browse/SUREFIRE-157?focusedCommentId=197215#comment-197215]
to that ticket also pointed to the late initialisation of the {{testResults}}
field.
