|

SYNOPSIS
|
||||
run_tests.py [OPTION]... [BUILD_DIR]... [TEST]...
|
||||
|
||||
DESCRIPTION
|
||||
Runs the specified tests (either binary or Python), and prints a
|
||||
summary of the results. BUILD_DIRS will be used to search for the
|
||||
binaries. If no TESTs are specified, all binary tests found in
|
||||
BUILD_DIRs and all Python tests found in the directory test/ (in the
|
||||
gtest root) are run.
|
||||
|
||||
TEST is a name of either a binary or a Python test. A binary test is
|
||||
an executable file named *_test or *_unittest (with the .exe
|
||||
extension on Windows) A Python test is a script named *_test.py or
|
||||
*_unittest.py.
|
||||
|
||||
OPTIONS
|
||||
-c CONFIGURATIONS
|
||||
Specify build directories via build configurations.
|
||||
CONFIGURATIONS is either a comma-separated list of build
|
||||
configurations or 'all'. Each configuration is equivalent to
|
||||
adding 'scons/build/<configuration>/gtest/scons' to BUILD_DIRs.
|
||||
Specifying -c=all is equivalent to providing all directories
|
||||
listed in KNOWN BUILD DIRECTORIES section below.
|
||||
|
||||
-a
|
||||
Equivalent to -c=all
|
||||
|
||||
-b
|
||||
Equivalent to -c=all with the exception that the script will not
|
||||
fail if some of the KNOWN BUILD DIRECTORIES do not exists; the
|
||||
script will simply not run the tests there. 'b' stands for
|
||||
'built directories'.
|
||||
|
||||
RETURN VALUE
|
||||
Returns 0 if all tests are successful; otherwise returns 1.
|
||||
|
||||
EXAMPLES
|
||||
run_tests.py
|
||||
Runs all tests for the default build configuration.
|
||||
|
||||
run_tests.py -a
|
||||
Runs all tests with binaries in KNOWN BUILD DIRECTORIES.
|
||||
|
||||
run_tests.py -b
|
||||
Runs all tests in KNOWN BUILD DIRECTORIES that have been
|
||||
built.
|
||||
|
||||
run_tests.py foo/
|
||||
Runs all tests in the foo/ directory and all Python tests in
|
||||
the directory test. The Python tests are instructed to look
|
||||
for binaries in foo/.
|
||||
|
||||
run_tests.py bar_test.exe test/baz_test.exe foo/ bar/
|
||||
Runs foo/bar_test.exe, bar/bar_test.exe, foo/baz_test.exe, and
|
||||
bar/baz_test.exe.
|
||||
|
||||
run_tests.py foo bar test/foo_test.py
|
||||
Runs test/foo_test.py twice instructing it to look for its
|
||||
test binaries in the directories foo and bar,
|
||||
correspondingly.
|
||||
|
||||
KNOWN BUILD DIRECTORIES
|
||||
run_tests.py knows about directories where the SCons build script
|
||||
deposits its products. These are the directories where run_tests.py
|
||||
will be looking for its binaries. Currently, gtest's SConstruct file
|
||||
defines them as follows (the default build directory is the first one
|
||||
listed in each group):
|
||||
On Windows:
|
||||
<gtest root>/scons/build/win-dbg8/gtest/scons/
|
||||
<gtest root>/scons/build/win-opt8/gtest/scons/
|
||||
<gtest root>/scons/build/win-dbg/gtest/scons/
|
||||
<gtest root>/scons/build/win-opt/gtest/scons/
|
||||
On Mac:
|
||||
<gtest root>/scons/build/mac-dbg/gtest/scons/
|
||||
<gtest root>/scons/build/mac-opt/gtest/scons/
|
||||
On other platforms:
|
||||
<gtest root>/scons/build/dbg/gtest/scons/
|
||||
<gtest root>/scons/build/opt/gtest/scons/

|
||||
SYNOPSIS
|
||||
run_tests.py [OPTION]... [BUILD_DIR]... [TEST]...
|
||||
|
||||
DESCRIPTION
|
||||
Runs the specified tests (either binary or Python), and prints a
|
||||
summary of the results. BUILD_DIRS will be used to search for the
|
||||
binaries. If no TESTs are specified, all binary tests found in
|
||||
BUILD_DIRs and all Python tests found in the directory test/ (in the
|
||||
%(proj)s root) are run.
|
||||
|
||||
TEST is a name of either a binary or a Python test. A binary test is
|
||||
an executable file named *_test or *_unittest (with the .exe
|
||||
extension on Windows) A Python test is a script named *_test.py or
|
||||
*_unittest.py.
|
||||
|
||||
OPTIONS
|
||||
-h, --help
|
||||
Print this help message.
|
||||
-c CONFIGURATIONS
|
||||
Specify build directories via build configurations.
|
||||
CONFIGURATIONS is either a comma-separated list of build
|
||||
configurations or 'all'. Each configuration is equivalent to
|
||||
adding 'scons/build/<configuration>/%(proj)s/scons' to BUILD_DIRs.
|
||||
Specifying -c=all is equivalent to providing all directories
|
||||
listed in KNOWN BUILD DIRECTORIES section below.
|
||||
-a
|
||||
Equivalent to -c=all
|
||||
-b
|
||||
Equivalent to -c=all with the exception that the script will not
|
||||
fail if some of the KNOWN BUILD DIRECTORIES do not exists; the
|
||||
script will simply not run the tests there. 'b' stands for
|
||||
'built directories'.
|
||||
|
||||
RETURN VALUE
|
||||
Returns 0 if all tests are successful; otherwise returns 1.
|
||||
|
||||
EXAMPLES
|
||||
run_tests.py
|
||||
Runs all tests for the default build configuration.
|
||||
run_tests.py -a
|
||||
Runs all tests with binaries in KNOWN BUILD DIRECTORIES.
|
||||
run_tests.py -b
|
||||
Runs all tests in KNOWN BUILD DIRECTORIES that have been
|
||||
built.
|
||||
run_tests.py foo/
|
||||
Runs all tests in the foo/ directory and all Python tests in
|
||||
the directory test. The Python tests are instructed to look
|
||||
for binaries in foo/.
|
||||
run_tests.py bar_test.exe test/baz_test.exe foo/ bar/
|
||||
Runs foo/bar_test.exe, bar/bar_test.exe, foo/baz_test.exe, and
|
||||
bar/baz_test.exe.
|
||||
run_tests.py foo bar test/foo_test.py
|
||||
Runs test/foo_test.py twice instructing it to look for its
|
||||
test binaries in the directories foo and bar,
|
||||
correspondingly.
|
||||
|
||||
KNOWN BUILD DIRECTORIES
|
||||
run_tests.py knows about directories where the SCons build script
|
||||
deposits its products. These are the directories where run_tests.py
|
||||
will be looking for its binaries. Currently, %(proj)s's SConstruct file
|
||||
defines them as follows (the default build directory is the first one
|
||||
listed in each group):
|
||||
On Windows:
|
||||
<%(proj)s root>/scons/build/win-dbg8/%(proj)s/scons/

<%(proj)s root>/scons/build/win-opt8/%(proj)s/scons/

||||
<%(proj)s root>/scons/build/win-dbg/%(proj)s/scons/
|
||||
<%(proj)s root>/scons/build/win-opt/%(proj)s/scons/
|
||||
On Mac:
|
||||
<%(proj)s root>/scons/build/mac-dbg/%(proj)s/scons/
|
||||
<%(proj)s root>/scons/build/mac-opt/%(proj)s/scons/
|
||||
On other platforms:
