+# How to Test
+
+This wiki page describes how to build and run tests on Linux. It should eventually provide guidance on how to add tests for a new feature.
+
+## Build Tests
+
+Can be built when you are building Orca Slicer binary by including the `-t` flag for `build_linux.sh`:
+
+```
+build_linux.sh -st
+```
+
+Test binaries will then appear under `build/tests`. As of this writing, not all tests will be built.
+
+## Run Unit Tests
+
+### Run All
+
+```
+ctest --test-dir build/tests
+```
+
+### Run a Specific Set
+
+```
+ctest --test-dir build/tests/slic3rutils
+```
