| 1278 | This abstract base class is meant to be subclassed. It provides default |
| 1279 | implementations for setUpClass(), tearDownClass(), setUp(), and tearDown(), |
| 1280 | among other things. |
| 1281 | |
| 1282 | Important things for test class writers: |
| 1283 | |
| 1284 | - Overwrite the mydir class attribute, otherwise your test class won't |
| 1285 | run. It specifies the relative directory to the top level 'test' so |
| 1286 | the test harness can change to the correct working directory before |
| 1287 | running your test. |
| 1288 | |
| 1289 | - The setUp method sets up things to facilitate subsequent interactions |
| 1290 | with the debugger as part of the test. These include: |
| 1291 | - populate the test method name |
| 1292 | - create/get a debugger set with synchronous mode (self.dbg) |
| 1293 | - get the command interpreter from with the debugger (self.ci) |
| 1294 | - create a result object for use with the command interpreter |
| 1295 | (self.res) |
| 1296 | - plus other stuffs |
| 1297 | |
| 1298 | - The tearDown method tries to perform some necessary cleanup on behalf |
| 1299 | of the test to return the debugger to a good state for the next test. |
| 1300 | These include: |
| 1301 | - execute any tearDown hooks registered by the test method with |
| 1302 | TestBase.addTearDownHook(); examples can be found in |
| 1303 | settings/TestSettings.py |
| 1304 | - kill the inferior process associated with each target, if any, |
| 1305 | and, then delete the target from the debugger's target list |
| 1306 | - perform build cleanup before running the next test method in the |
| 1307 | same test class; examples of registering for this service can be |
| 1308 | found in types/TestIntegerTypes.py with the call: |
| 1309 | - self.setTearDownCleanup(dictionary=d) |
| 1310 | |
| 1311 | - Similarly setUpClass and tearDownClass perform classwise setup and |
| 1312 | teardown fixtures. The tearDownClass method invokes a default build |
| 1313 | cleanup for the entire test class; also, subclasses can implement the |
| 1314 | classmethod classCleanup(cls) to perform special class cleanup action. |
| 1315 | |
| 1316 | - The instance methods runCmd and expect are used heavily by existing |
| 1317 | test cases to send a command to the command interpreter and to perform |
| 1318 | string/pattern matching on the output of such command execution. The |
| 1319 | expect method also provides a mode to peform string/pattern matching |
| 1320 | without running a command. |
| 1321 | |
| 1322 | - The build methods buildDefault, buildDsym, and buildDwarf are used to |
| 1323 | build the binaries used during a particular test scenario. A plugin |
| 1324 | should be provided for the sys.platform running the test suite. The |
