Enforcing DRY principles -- Optimization of test suites

Describe the enhancement Currently, there are many tests that are repetitive, i.e: For example:

def test_issue_comments_mean_std_by_group(metrics):
    response = requests.get('http://localhost:5000/api/unstable/repo-groups/10/issue-comments-mean-std')
    data = response.json()
    assert response.status_code == 200
    assert len(data) >= 1

def test_issue_comments_mean_std_by_repo(metrics):
    response = requests.get('http://localhost:5000/api/unstable/repo-groups/10/repos/25430/issue-comments-mean-std')
    data = response.json()
    assert response.status_code == 200
    assert len(data) >= 1

def test_issue_comments_mean_std_by_repo(metrics):
    response = requests.get('http://localhost:5000/api/unstable/repo-groups/10/repos/25430/issue-comments-mean-std')
    data = response.json()
    assert response.status_code == 200
    assert len(data) >= 1

Instead of this, we could write a common function that could be called across these tests to incorporate readability, reusability and proper maintenance.

Additional info Working on this.

@mrsaicharan1 : OK … you might need to open a new PR, as we merged the first one!

Great!
