+This test case verifies [filtering applications by name](https://argocd-image-updater.readthedocs.io/en/stable/install/reference/#flags) with `--match-application-name` command line options
+* match against a non-existent application name
+* match against an exact application name
+* specify `--match-application-name` option multiple times to match against multiple application names
+* use wild card `*` in application name pattern
+
+This test case uses image from public container registry and application source from public GitHub repo.
+
+To run this individual test case,
+
+* make sure both docker daemon and k8s cluster is running
+* `cd $HOME/go/src/image-updater/test/e2e`
+* `SRC_DIR=$HOME/go/src/image-updater kubectl kuttl test --namespace argocd-image-updater-e2e --timeout 120 --test 102-kustomize-match-application-name`
+
+The test output logs that during each test step, 0, 1, 2, or 3 images are updated, as specified by argocd-image-updater `--match-application-name` option:
+```bash
