"""Invokes a test function and translates Python exceptions into test results.
|
|
|
|
This method invokes SetUp()/TearDown() on the test. It is intended to be
|
|
resilient to exceptions in SetUp(), the test itself, and TearDown(). Any
|
|
Python exception means the test is marked as failed, and the test result will
|
|
contain information about the exception.
|
|
|
|
If SetUp() raises an exception, the test is not run.
|
|
|
|
If TearDown() raises an exception, the test is treated as a failure. However,
|
|
if the test itself raised an exception beforehand, that stack trace will take
|
|
precedence whether or not TearDown() also raised an exception.
|
|
|
|
shard_index is not applicable in single-device scenarios, when test execution
|
|
is serial rather than parallel. Tests can use this to bring up servers with
|
|
unique port numbers, for example. See also python_test_sharder.
|
|
|
|
Args:
|
|
test: an object which is ostensibly a subclass of PythonTestBase.
|
|
options: Options to use for setting up tests.
|
|
|
|
Returns:
|
|
A TestResults object which contains any results produced by the test or, in
|
|
the case of a Python exception, the Python exception info.
