Hello,
There weren't any tests for testcover.el, so I wrote some.

+;;; Commentary:
+
+;; * This file should not be loaded directly. It is meant to be read
+;; by `testcover-tests-build-test-cases'.
+;;
+;; * Test cases begin with ;; ==== name ====. The symbol name between
+;; the ===='s is used to create the name of the test.
+;;
+;; * Following the beginning comment place the test docstring and
+;; any tags or keywords for ERT. These will be spliced into the
+;; ert-deftest for the test.
+;;
+;; * To separate the above from the test case code, use another
+;; comment: ;; ====
+;;
+;; * These special comments should start at the beginning of a line.
+;;
+;; * `testcover-tests-skeleton' will prompt you for a test name and
+;; insert the special comments.
+;;
+;; * The test case code should be annotated with %%% at the end of
+;; each form where a tan splotch is expected, and !!! at the end
+;; of each form where a red mark is expected.
+;;
+;; * If Testcover is working correctly on your code sample, using
+;; `testcover-tests-markup-region' and
+;; `testcover-tests-unmarkup-region' can make creating test cases
+;; easier.

Thanks. When I run the tests, this doesn't compile for me:
Compiling lisp/emacs-lisp/testcover-tests.el
In toplevel form:

Sorry I missed that. It doesn't compile for me either, nor does it break
running the tests on my machine although it looks like it's supposed to,
and I was in the habit of just looking at the log file not make's
output.
Since the way testcover-tests.el builds tests depends on the runtime
environment to find testcases.el, the simplest fix is to add
no-byte-compile to the file local variables which I have done in this
version:

+;;; Commentary:
+
+;; * This file should not be loaded directly. It is meant to be read
+;; by `testcover-tests-build-test-cases'.
+;;
+;; * Test cases begin with ;; ==== name ====. The symbol name between
+;; the ===='s is used to create the name of the test.
+;;
+;; * Following the beginning comment place the test docstring and
+;; any tags or keywords for ERT. These will be spliced into the
+;; ert-deftest for the test.
+;;
+;; * To separate the above from the test case code, use another
+;; comment: ;; ====
+;;
+;; * These special comments should start at the beginning of a line.
+;;
+;; * `testcover-tests-skeleton' will prompt you for a test name and
+;; insert the special comments.
+;;
+;; * The test case code should be annotated with %%% at the end of
+;; each form where a tan splotch is expected, and !!! at the end
+;; of each form where a red mark is expected.
+;;
+;; * If Testcover is working correctly on your code sample, using
+;; `testcover-tests-markup-region' and
+;; `testcover-tests-unmarkup-region' can make creating test cases
+;; easier.

If it's important to be able to run the tests compiled, I could move all
the testcases into strings in testcover-tests.el, but they are easier to
read and edit when in their own file.

I suggest instead using eval-and-compile, as in the attached patch.

+;;; Commentary:
+
+;; * This file should not be loaded directly. It is meant to be read
+;; by `testcover-tests-build-test-cases'.
+;;
+;; * Test cases begin with ;; ==== name ====. The symbol name between
+;; the ===='s is used to create the name of the test.
+;;
+;; * Following the beginning comment place the test docstring and
+;; any tags or keywords for ERT. These will be spliced into the
+;; ert-deftest for the test.
+;;
+;; * To separate the above from the test case code, use another
+;; comment: ;; ====
+;;
+;; * These special comments should start at the beginning of a line.
+;;
+;; * `testcover-tests-skeleton' will prompt you for a test name and
+;; insert the special comments.
+;;
+;; * The test case code should be annotated with %%% at the end of
+;; each form where a tan splotch is expected, and !!! at the end
+;; of each form where a red mark is expected.
+;;
+;; * If Testcover is working correctly on your code sample, using
+;; `testcover-tests-markup-region' and
+;; `testcover-tests-unmarkup-region' can make creating test cases
+;; easier.
