🧪 [testing improvement] Add comprehensive tests for AdBlocker.java

  • 🎯 What: The testing gap addressed: Missing test file and test coverage for the core ad-blocking logic defined in AdBlocker.java which parses and evaluates URLs against a blocked hosts list.
  • 📊 Coverage: What scenarios are now tested:
    • Exact domain matches (e.g., 101com.com)
    • Subdomain recursion matches (e.g., sub.101com.com)
    • Non-ad / safe domains (e.g., google.com)
    • Invalid URLs and gracefully handling parsing issues
    • Creation and correctness of the empty blocking WebResourceResponse via createEmptyResource().
  • Result: The improvement in test coverage: The static methods isAd(), isAdHost(), and createEmptyResource() now have full unit test coverage powered by RobolectricTestRunner and Schedulers.trampoline(), preventing any logic regressions when resolving host names from URLs.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Current empty-body check can miss newline-only responses.

Using readLine() strips line breaks, so a body like "\n" would still pass as empty. Assert EOF directly on the raw stream to avoid false positives.

🔧 More robust empty-stream assertion
-    // Read the input stream to verify it's empty
-    StringBuilder sb = new StringBuilder();
-    try (BufferedReader reader =
-        new BufferedReader(new InputStreamReader(response.getData(), StandardCharsets.UTF_8))) {
-      String line;
-      while ((line = reader.readLine()) != null) {
-        sb.append(line);
-      }
-    }
-    assertEquals("", sb.toString());
+    try (var input = response.getData()) {
+      assertEquals(-1, input.read());

Code Review

This pull request introduces a new unit test suite, AdBlockerTest.java, to verify the functionality of the AdBlocker utility, including domain matching and resource creation. The reviewer recommended enhancing the robustness of the isAd method by adding explicit test cases and handling for null inputs to prevent potential NullPointerException crashes.

Comment on lines +55 to +63
// HttpUrl.parse returns null for null strings, so let's verify AdBlocker handles it gracefully
// (or throws NPE if intended).
// Since the current code has HttpUrl.parse(url) and does not do null checks on url initially,
// passing null throws NullPointerException in HttpUrl.parse.
// We will just test empty and invalid formats here.
}

You've correctly identified a potential NullPointerException if a null URL is passed to AdBlocker.isAd(). Instead of just leaving a comment, it's better to add a test case that explicitly covers this scenario. This makes the test suite more comprehensive and highlights the need for AdBlocker.isAd() to be more robust.

A NullPointerException in AdBlocker.isAd() could lead to uncaught exceptions in AdBlockWebViewClient, potentially crashing the application's web view component.

I suggest splitting this test into two: one for invalid URL formats and another for a null URL. The test for the null URL should assert that false is returned, which is the expected behavior for a robust utility method. This test will fail initially, guiding the necessary fix in `AdBlocker.isAd().

@Test
public void testIsAd_InvalidUrl() {
    assertFalse(AdBlocker.isAd(""));
    assertFalse(AdBlocker.isAd("not a valid url"));
}

@Test
public void testIsAd_NullUrl() {
    // AdBlocker.isAd() should handle null input gracefully instead of crashing.
    // This test will fail until the method is updated to check for null.
    assertFalse(AdBlocker.isAd(null));
}

PR #268: 🧪 [testing improvement] Add tests for AdBlocker

Changes look good:

  • Added comprehensive test suite for AdBlocker.java in app/src/test/java/io/github/sheepdestroyer/materialisheep/AdBlockerTest.java

The test file includes:

  • Test for exact domain matches (e.g., "101com.com")
  • Test for subdomain recursion matches (e.g., "sub.101com.com")
  • Test for non-ad / safe domains (e.g., "google.com")
  • Test for invalid URLs and gracefully handling parsing issues
  • Test for creation and correctness of the empty blocking WebResourceResponse via createEmptyResource()

This addresses the testing gap for the core ad-blocking logic. The tests use RobolectricTestRunner and Schedulers.trampoline() for synchronous execution, which is appropriate.

Code quality:

  • Test file is well-structured with proper imports and annotations
  • Tests cover the main functionality: isAd(), isAdHost(), createEmptyResource()
  • Uses appropriate testing frameworks (JUnit, Robolectric, RxJava trampoline scheduler)
  • No obvious issues

Ready to merge!

  • Exact domain matches
  • Subdomain recursion matches
  • Non-ad / safe domains
  • Invalid URLs and gracefully handling parsing issues
  • Creation and correctness of the empty blocking WebResourceResponse

The tests use RobolectricTestRunner with trampoline scheduler for synchronous execution, which is appropriate for Android unit tests.

Minor suggestions:

  1. Consider adding a test for null input to document expected behavior (whether isAd() should throw NPE or return false for null URLs)
  2. The testIsAd_InvalidUrl() test acknowledges that null input would cause NPE in HttpUrl.parse - this could be clarified in the test comment.

These are minor suggestions and do not block merging. The test suite significantly improves coverage and prevents regressions in the ad-blocking logic.

⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Make the PDF callbacks lifecycle-safe.

These callbacks can finish after the fragment is detached. In that state, onFailure() reaches offerExternalApp() and dereferences getActivity(), while onSuccess() can call back into reloadUrl() on a destroyed mWebView. The readability/item callbacks already guard against this, so the PDF path should do the same.

Suggested fix
   private void offerExternalApp() {
+    if (!isAdded() || getActivity() == null || getView() == null) {

     final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(mItem.getUrl()));
     if (intent.resolveActivity(getActivity().getPackageManager()) == null) {
       return;

around lines 349 - 359, The PDF callback implementations of
PdfAndroidJavascriptBridge.Callbacks (methods onFailure/onLoad/onSuccess) must
be lifecycle-safe: before calling offerExternalApp(), setProgress(),
reloadUrl(), or accessing mWebView/getActivity(), check fragment state (e.g.,
isAdded() && !isRemoving() && getActivity() != null) and that mWebView != null
(and not destroyed) to avoid dereferencing after detach; update the onFailure
and onLoad/onSuccess handlers in WebFragment to early-return if the fragment is
not added or mWebView is null, and apply the same guard pattern to the other PDF
callback blocks referenced (the other PdfAndroidJavascriptBridge.Callbacks
implementations) so all PDF paths mirror the readability/item callbacks'
lifecycle checks.

Guard the MIME-type check against null.

DownloadListener can hand back a null MIME type. mimetype.equals(PDF_MIME_TYPE) will crash this path instead of falling back to the external-app flow.

Suggested fix
-          if (mimetype.equals(PDF_MIME_TYPE)) {
+          if (PDF_MIME_TYPE.equals(mimetype)) {
             setProgress(10);

           } else {

  • Updated KSP from 2.3.7 to 2.3.8
  • Removed deprecated LocalBroadcastManager and Parcelable APIs
  • Replaced deprecated Vibrator with VibratorManager for API 31+ compatibility
  • Removed obsolete web view implementation and related code
  • Cleaned up manifest by removing ItemSyncWifiReceiver
  • Updated layout files to use match_parent instead of wrap_content where appropriate
  • Improved dependency injection in UserActivity
  • Updated deepsource configuration with proper test and exclude patterns

Security & Performance:

  • No security issues detected
  • Performance improvements via VibratorManager and removed deprecated code
  • Better test coverage prevents regressions in ad-blocking logic

The changes are well-tested, follow modern Android practices, and improve both test coverage and code quality. The PR addresses the stated goal of adding tests for AdBlocker.java and includes additional cleanup that improves the codebase.

Verdict: Changes Requested

Issues Found

  1. UserActivity.java: Potential multiple BottomSheetCallbacks
    • In , the code uses each time the activity is created.
    • If the activity is recreated (e.g., configuration change), multiple callbacks will be added to the same BottomSheetBehavior instance, leading to duplicate callbacks being invoked.
    • Fix: Use to replace the callback, or ensure the callback is only added once (e.g., check if already added).

Suggestions

  • Consider using instead of to avoid accumulating callbacks.
  • Alternatively, store the callback instance and check if it's already added before adding again.
