Grouping assertions

Created by: eas5

Problem: A test method with many individual assertions stops being executed on the first failed assertion, which prevents the execution of the remaining ones.

Solution: By using the JUnit5 grouped assertions feature, all assertions are executed and all failures will be reported together. In this refactoring, no original assertion was changed.

Result: Before:

        assertFalse(pathMatcher.match("/admin/?*/**", "/admin"));
        assertFalse(pathMatcher.match("/admin/?*/**", "/admin/"));
        assertTrue(pathMatcher.match("/admin/?*/**", "/admin/index.html"));
        assertTrue(pathMatcher.match("/admin/?*/**", "/admin/index.html/more"));

After:

        assertAll(
            () -> assertFalse(pathMatcher.match("/admin/?*/**", "/admin")),
            () -> assertFalse(pathMatcher.match("/admin/?*/**", "/admin/")),
            () -> assertTrue(pathMatcher.match("/admin/?*/**", "/admin/index.html")),
            () -> assertTrue(pathMatcher.match("/admin/?*/**", "/admin/index.html/more"))
        );
