I spent a lot time on researching what is a convenient way to test custom Lint rules. I didn't like the AbstractCheckTestsince it has too many "non-public" dependencies on the one hand and its assertion mechanism is very poor on the other hand.

EDIT:
I finally created a JUnit rule for that. It basically wraps the original mechanism Android uses internally - but it allows more advanced assertions and is very straight forward to use.

Maybe it is also interesting for your use case.
https://github.com/a11n/lint-junit-rule

@Rule public Lint lint = new Lint(new MyCustomRule(), MyCustomRule.ISSUE);

  @Test
  public void test() throws Exception {
    List<Warning> lintResult = lint.files("AndroidManifest.xml", "res/values/string.xml");

    //AssertJ
    assertThat(lintResult)
      .hasWarnings(2)
      .in("AndroidManifest.xml", "string.xml")
      .atLine(8, 14)
      .withMessage("MyCustomRule warning message.",
                   "MyCustomRule warning message.");

    //Hamcrest
    assertThat(lintResult,
                hasWarnings(
                  in("AndroidManifest.xml", "string.xml"),
                  atLine(8, 14),
                  withMessage("MyCustomRule warning message.",
                              "MyCustomRule warning message.")));
  }

Since com.android.tools.lint.checks.infrastructure.LintDetectorTest; is now available, it might be the best solution

I agree.

(Although I still don't like the poor assertion capabilities and the JUnit3-style.)
