+# Tests for POM
+
+Each subdirectory of this directory contains a type of test for POM parsers.
+They are described below:
+
+- `parsing/` — for testing that key-value pairs are correct
+- `location/` — for testing that definition location of keys is correctly determined
+- `errors/` — for testing that error conditions are detected and gracefully handled
+- `interpretation/` — for testing that numbers, booleans, and lists are parsed correctly
+- `schema/` — for testing that schemas are implemented correctly

+Each test in this file has an error,

+# Location tests
+
+These tests are for checking that definition location information
+is correctly recorded.
+
+Each test consists of a file `x.pom` and a file `x.locations.pom`.
+For every key in `x.pom`, there’s a corresponding key in `x.locations.pom`
+which is set to the line number where the key was defined in `x.pom`.

 # Parsing tests
 
-These tests only check that key-value pairs are parsed correctly.
-They do not test merging, number/list parsing, or schema validation.
+These tests are for checking that key-value pairs are parsed correctly.
 
 Each test `x` consists of two files, `x.pom` and `x.flat.pom`. These
 files should produce the exact same schema, but `x.flat.pom` is formatted
