+# src/testing
+
+Here is an example usage of the testing
+
+This is from "lexer/test_lexer.c"
+
+For each module of code, create a test_{module_name} file.
+This file should include a test_{module_name} function that includes the testing_setup and the testing_cleanup functions.
+
+```c
+#include "lex.h"
+#include <testing/test_utils.h>
+
+int test_lexer() {
+    testing_module_setup();
+
+    test_ttype_from_string();
+
+    testing_module_cleanup();
+    return 0;
+}
+```
+
+After this, include a call to this function in the "testing/main.c" file like how it's done for test_lexer.
+
+```c
+#include "lexer/test_lexer.h"
+
+int main() {
+        test_lexer();
+
+        return 0;
+}
+```
+
+Finally, here is what a test might look like. Make sure to include a call to testing_func_setup at the start.
+
+```c
+int test_ttype_from_string() {
+	testing_func_setup();
+
+    tassert(ttype_from_string("1") == TT_LITERAL);
+    tassert(ttype_from_string("1.2") == TT_LITERAL);
+
+	// ...
+
+    tassert(ttype_from_string(";") == TT_SEMI);
+
+    return 0;
+}
+```
