Note that in this particular example we are planning on building a custom Ant task so we set the includeAntRuntime attribute. Typically, you should set this attribute to false, to control your classpaths better. We follow the compilation with a <copy> task to bring over all non-.java resources into the testing classpath, which will allow our tests to access test data easily. Because of dependency checking, the <copy> task does not impact incremental build times until those files change.

By default, failing test cases run with <junit> do not fail the build process. The authors believe that this behavior is somewhat backwards and the default should be to fail the build: you can set the haltonfailure attribute to true to achieve this result.3 Developers must treat test failures in the same urgent regard as compilation errors, and give them the same show-stopping attention. Adding both haltonfailure="true" and printsummary="true" to our <junit> element attributes, we now get the following output:

Our build has failed because our test case failed, exactly as desired. The summary output provides slightly more details: how many tests run, how many failed, and how many had errors. We still are in the dark about what caused the failure, but not for long. 4.6.1 Capturing test results The JUnit task provides several options for collecting test result data by using formatters. One or more <formatter> tags can be nested either directly under <junit> or under the <test> (and <batchtest>, which we will explore shortly). Ant includes three types of formatters shown in table 4.2.

Table 4.2
Ant JUnit task result formatter types.
<formatter> type Description brief plain xml Provides details of test failures in text format. Provides details of test failures and statistics of each test run in text format. Provides an extensive amount of detail in XML format including Ant s properties at the time of testing, system out, and system error output of each test case.
By default, <formatter> output is directed to files, but can be directed to Ant s console output instead. Updating our single test case run to include both the build failure upon test failure and detailed console output, we use this task declaration:
<junit printsummary="false" haltonfailure="true"> <classpath refid="test.classpath"/> <formatter type="brief" usefile="false"/> <test name="org.example.antbook.ant.lucene.HtmlDocumentTest"/> </junit>
This produces the following output:
[junit] Testsuite: org.example.antbook.ant.lucene.HtmlDocumentTest [junit] Tests run: 1, Failures: 1, Errors: 0, Time elapsed: 0.01 sec [junit] [junit] Testcase: testDoc(org.example.antbook.ant.lucene .HtmlDocumentTest):FAILED [junit] Title expected:<Test Title> but was:<null> [junit] junit.framework.AssertionFailedError: Title expected:<Test Title> but was:<null> [junit] at org.example.antbook.ant.lucene .HtmlDocumentTest.testDoc(HtmlDocumentTest.java:20) [junit] [junit] BUILD FAILED
Now we re getting somewhere. Tests run as part of our regular build, test failures cause our build to fail, and we get enough information to see what is going on. By default, formatters write their output to files in the directory specified by the <test> or <batchtest> elements, but usefile="false" causes the formatters to write to the Ant console instead. It s worth noting that the stack trace shown is abbreviated by the formatter, showing only the most important pieces rather than line numbers tracing back into JUnit s classes. Also, we turned off the printsummary option as it duplicates and interferes with the output from the brief formatter. XML formatter Using the brief formatter directed to Ant s console is very useful, and definitely recommended to allow quick inspection of the results and details of any failures. The <junit> task allows more than one formatter, so you can direct results toward

TESTING WITH JUNIT
several formatters at a time. Saving the results to XML files lets you process them in a number of ways. Our testing task now evolves to this:
<junit printsummary="false" haltonfailure="true"> <classpath refid="test.classpath"/> <formatter type="brief" usefile="false"/> <formatter type="xml"/> <test todir="${test.data.dir}" name="org.example.antbook.ant.lucene.HtmlDocumentTest"/> </junit>
The effect of this is to create an XML file for each test case run in the ${test.data.dir} directory. In this example, the file name will be TEST-org. example.antbook.ant.lucene.HtmlDocumentTest.xml. Viewing System.out and System.err output While it is typically unnecessary to have test cases write to standard output or standard error, it might be helpful in troubleshooting. With no formatters specified and printsummary either on or off, the <junit> task swallows the output. A special value of printsummary lets you pass this output through back to Ant s output: printsummary="withOutAndErr". The plain, brief, and xml formatters capture both output streams, so in our example printsummary is disabled because we use the brief formatter to output to the console instead. With a System.out.println("Hi from inside System.out.println") inside a testOutput method of SimpleTest, our output is
test: [junit] Testsuite: org.example.antbook.junit.SimpleTest [junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 0.09 sec [junit] ------------- Standard Output --------------[junit] Hi from inside System.out.println [junit] ------------- ---------------- --------------[junit] [junit] Testcase: testSomething took 0.01 sec [junit] Testcase: testOutput took 0 sec [junitreport] Using Xalan version: 2.1.0 [junitreport] Transform time: 932ms BUILD SUCCESSFUL Total time: 2 seconds.
Note that it does not identify the test method, testOutput in this case, which generated the output. 4.6.2 Running multiple tests So far, we ve only run a single test case using the <test> tag. You can specify any number of <test> elements but that is still time consuming. Developers should not have to edit the build file when adding new test cases. Enter <batchtest>. You can nest filesets within <batchtest> to include all your test cases. 99
