 We aim to to improve this to a 100% pass rate soon.
 
+**Running the Test Suite**  
+Before running the tests, make sure you have [set-up ext4-DAX](#set-up-ext4-DAX)  
+
+To run tests in all modes:  
+```
+$ make test
+```
+To run tests in a specific mode:
+```
+$ make -C tests pjd.<mode>
+```
+where `<mode>` is one of `posix`, `sync` or `strict`.  Example: `make -C tests pjd.posix`  
+
+Tip: Redirect stderr for less verbose output: e.g `make test 2>/dev/null`
