+# Testing STASIS
+
+## Unit tests
+
+Rules:
+
+* Use the boilerplate `_test_boilerplate.c`
+  * ```shell
+    cp _test_boilerplate.c test_mynewtest.c
+    ```
+* Test file names start with `test_` (`test_file.c`)
+* Test functions start with `test_` (`void test_function()`)
+* Test suites can be skipped by returning `127` from `main()`
+* PASS, FAIL, and SKIP conditions are set by the assertion macros `STASIS_{ASSERT,ASSERT_FATAL,SKIP_IF}`
+* Parametrized tests should implement an array of `struct testcase`
+  * The `testcase` structure should be local to each `test_` function
+  * The `testcase` variables are freeform
+  * Example:
+    ```c
+    void test_function() {
+        struct testcase {
+            int your;
+            int variables;
+            int here;
+        };
+        struct testcase tc[] = {
+            {.your = 0, .variables = 1, .here = 2},
+            {.your = 3, .variables = 4, .here = 5},
+            // ...
+        };
+        for (size_t i = 0; i < sizeof(tc) / sizeof(*tc); i++) {
+            // STASIS_ASSERT()s here
+        }
+    }
+    ```
+    
+## Regression test (RT)
+
+Rules:
+
+* Regression tests are shell scripts (BASH)
+* Use the boilerplate `_rt_boilerplate.sh`
+  * ```shell
+    cp _rt_boilerplate.sh rt_mynewtest.sh
+    ```
+* Test file names start with `rt_` (`rt_file.sh`)
+* Test function names are freeform, however they must be executed using `run_command()` (`run_command test_function`)
+* Test suites can be skipped by returning `127` from the shell script
