style='font-size:12.0pt'>Hi Neelima,<br>
<br>
If you're building the test executable(s) using CMake already and assuming you
have a variable like ${GTEST_SOURCE_FILES} which is a list of all your test
source files, you could probably get away without using a script to generate a
list of names by doing something like:<br>
<br>
</span></font><code><font size=2 face="Courier New"><span style='font-size:
10.0pt'>FOREACH(GTEST_SOURCE_FILE ${GTEST_SOURCE_FILES})</span></font></code><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<code><font face="Courier New"> FILE(STRINGS ${GTEST_SOURCE_FILE}
GTEST_NAMES REGEX ^TEST)</font></code><br>
<code><font face="Courier New"> FOREACH(GTEST_NAME ${GTEST_NAMES})</font></code><br>
<code><font face="Courier New"> STRING(REGEX REPLACE
["\) \(,"] ";" GTEST_NAME ${GTEST_NAME})</font></code><br>
<code><font face="Courier New"> LIST(GET GTEST_NAME 1
GTEST_GROUP_NAME)</font></code><br>
<code><font face="Courier New"> LIST(GET GTEST_NAME 3
GTEST_NAME)</font></code><br>
<code><font face="Courier New">
ADD_TEST(${GTEST_GROUP_NAME}.${GTEST_NAME}
${EXECUTABLE_OUTPUT_PATH}/${BIN_NAME}
--gtest_filter=${GTEST_GROUP_NAME}.${GTEST_NAME})</font></code><br>
<code><font face="Courier New"> ENDFOREACH()</font></code><br>
<code><font face="Courier New">ENDFOREACH()</font></code><br>
<br>
</span></font>This relies on the tests each being defined by the Gtest macro
TEST(test fixture, test name) or TEST_F(test fixture, test name) in the source
files, but it would avoid the need to have the test executable built before
running the ADD_TEST command.<br>
<br>
Cheers,<br>
<br>
Fraser.<br>

software. We are using CMake (version 4.6-patch 2) for building the
unit tests executable. Since the list of unit tests is expected to grow
to thousands of tests, I am looking for a way to automate creating a file (say
testlist) on the fly that will contain the list of all our unit tests specified
using the CTest ADD_TEST command. My thought was to use INCLUDE(testlist) to
read in the list of tests at the appropriate point in the CMakeLists.txt
file(i.e, just after calling ENABLE_TESTING().<u5:p></u5:p></span></font><o:p></o:p></p>
