+## Build HIP tests
+
+### Build HIP directed tests
+Developers can build HIP directed tests right after build HIP commands,
+
+```
+sudo make install
+make -j$(nproc) build_tests
+```
+By default, all HIP directed tests will be built and generated under the folder $HIPAMD_DIR/build/directed_tests.
+Take HIP directed device APIs tests, as an example, all available test applications will have executable files generated under,
+$HIPAMD_DIR/build/directed_tests/runtimeApi/device.
+
+Run all HIP directed_tests, use the command,
+
+```
+ctest
+```
+Or
+```
+make test
+```
+
+Build and run a single directed test, use the follow command as an example,
+
+```
+make directed_tests.texture.hipTexObjPitch
+cd $HIPAMD_DIR/build/directed_tests/texcture
+./hipTexObjPitch
+```
+Please note, the integrated HIP directed tests, will be deprecated in future release.
+
+
+### Build HIP catch tests
+
+After build and install HIP commands, catch tests can be built via the following instructions,
+
+```
+cd "$HIP_DIR"
+mkdir -p build; cd build
+export HIP_PATH=$HIPAMD_DIR/build
+cmake  ../tests/catch/ -DHIP_PLATFORM=amd
+make -j$(nproc) build_tests
+ctest # run tests
+```
+
+HIP catch tests are built under the folder $HIP_DIR/build.
+
+To run a single catch test, the following is an example,
+
+```
+cd $HIP_DIR/build/unit/texture
+./TextureTest
+```
+
+### Build HIP Catch2 standalone test
+
+HIP Catch2 supports build a standalone test, for example,
+
+```
+export PATH=$HIP_DIR/bin:$PATH
+export HIP_PATH=$HIPAMD_DIR/build/install
+
+hipcc $HIP_DIR/tests/catch/unit/memory/hipPointerGetAttributes.cc -I ./tests/catch/include ./tests/catch/hipTestMain/standalone_main.cc -I ./tests/catch/external/Catch2 -g -o hipPointerGetAttributes
+./hipPointerGetAttributes
+...
+
+All tests passed
+```
+
+HIP catch tests, especially new architectured Catch2, will be official HIP tests in the repository and can be built alone as with the instructions shown above.
