+## Tests Changed Report
+
+### Overview
+
+Displays tests that have been added or removed compared to a baseline or previous run. This report helps track test suite evolution over time by showing exactly which tests are new and which have been removed. Each test is listed with its name and suite hierarchy, making it easy to identify changes in your test coverage.
+
+Requires previous test results or a baseline for comparison.
+
+### Usage
+
+Set the `tests-changed-report` input to true in your workflow configuration:
+
+```yaml
+- name: Publish Test Report
+  uses: ctrf-io/github-test-reporter@v1
+  with:
+    report-path: './ctrf/*.json'
+    tests-changed-report: true
+  if: always()
