GTestResultParser

public class GTestResultParser
extends MultiLineReceiver

java.lang.Object
   ↳ com.android.ddmlib.MultiLineReceiver
     ↳ com.android.tradefed.testtype.GTestResultParser

Parses the 'raw output mode' results of native tests using GTest that run from shell, and informs a ITestInvocationListener of the results.

Sample format of output expected: 

 [==========] Running 15 tests from 1 test case.
 [----------] Global test environment set-up.
 [----------] 15 tests from MessageTest
 [ RUN      ] MessageTest.DefaultConstructor
 [       OK ] MessageTest.DefaultConstructor (1 ms)
 [ RUN      ] MessageTest.CopyConstructor
 external/gtest/test/gtest-message_test.cc:67: Failure
 Value of: 5
 Expected: 2
 external/gtest/test/gtest-message_test.cc:68: Failure
 Value of: 1 == 1
 Actual: true
 Expected: false
 [  FAILED  ] MessageTest.CopyConstructor (2 ms)
  ...
 [ RUN      ] MessageTest.DoesNotTakeUpMuchStackSpace
 [       OK ] MessageTest.DoesNotTakeUpMuchStackSpace (0 ms)
 [----------] 15 tests from MessageTest (26 ms total)

 [----------] Global test environment tear-down
 [==========] 15 tests from 1 test case ran. (26 ms total)
 [  PASSED  ] 6 tests.
 [  FAILED  ] 9 tests, listed below:
 [  FAILED  ] MessageTest.CopyConstructor
 [  FAILED  ] MessageTest.ConstructsFromCString
 [  FAILED  ] MessageTest.StreamsCString
 [  FAILED  ] MessageTest.StreamsNullCString
 [  FAILED  ] MessageTest.StreamsString
 [  FAILED  ] MessageTest.StreamsStringWithEmbeddedNUL
 [  FAILED  ] MessageTest.StreamsNULChar
 [  FAILED  ] MessageTest.StreamsInt
 [  FAILED  ] MessageTest.StreamsBasicIoManip
 9 FAILED TESTS

where the following tags are used to signal certain events: 

 [==========]: the first occurrence indicates a new run started, including the number of tests
                  to be expected in this run
 [ RUN      ]: indicates a new test has started to run; a series of zero or more lines may
                  follow a test start, and will be captured in case of a test failure or error
 [       OK ]: the preceding test has completed successfully, optionally including the time it
                  took to run (in ms)
 [  FAILED  ]: the preceding test has failed, optionally including the time it took to run (in ms)
 [==========]: the preceding test run has completed, optionally including the time it took to run
                  (in ms)
All other lines are ignored.
