How to write test for this method?

[lpopek]

public static String getBaseURL() {   
    return ComponentAccessor.getApplicationProperties().getString("jira.baseurl");
}

or this method? 

public boolean issuesHaveSameProject(Issue firstIssue, Issue secondIssue) {
    Long firstId = firstIssue.getProjectId();
    Long secondId = secondIssue.getProjectId();
    return firstId.equals(secondId);
}

Should I use Mockito?
