One of the significant things to know about Regression Testing services is that it works best when running early and frequently during each sprint. This is because running them later in the development cycle might yield unfavorable test results.

1. Test Cases, Challenges And Objectives
Of Regression Testing

2. A growing number of software development teams today
favour agile software development over other
development strategies.
There’s no requirement to introduce Agile, but let’s return
to it anyway! We know that the agile development
methodology is adaptive in nature.
It concentrates on creating a product based on empirical
feedback associated with frequent testing by breaking
down the product development means into shorter
development cycles or sprints.
Supports All Programming Languages
Similar to influential operating systems and web
browsers, Selenium also helps a large number of
programming languages like Java, C#, Python, and Ruby.
The feature makes the tool effective in testing all kinds of
web application despite the programming language used
by code writers.

3. Test Cases For Regression Testing
It was observed from industry data that the good number of the
bugs reported by clients were due to last minute glitch fixes to
build side effects and therefore selecting the Test Case for
regression testing is an art and not that easy.
Effective Regression Tests Can Be Performed By
Selecting Following Test Cases –
• Sample of Failure test cases.
• Sample of Successful test cases.
• Boundary value test cases.
• All Complex Test Cases.
• All Integration Test Cases.
• Test cases of Functionalities which has undergone more and
recent changes.
• Test cases which verify core features of the product.
• Functionalities which are more visible to the users.
• Test cases which have frequent defects.

4. An Incomplete Regression Test Plan: One of the significant
things to know about Regression Testing services is that it
works best when running early and frequently during each
sprint. This is because running them later in the
development cycle might yield unfavourable test results.
Perform automated metrics against test scripts based on
changes to the application.
• Version control test scripts and software attributes.
• Maintain test scripts and document software
attributes.
• Document of the application development workflow.
• Transform the workflow into test scripts.
For the benefit of reduced deadlines, automated
incremental regression testing exposed various more
errors than were initially anticipated.
Regression test automation also discovers new defects
that may have arisen from new fixes.

5. Challenges of Regression Testing
Communicating Business Value:
Regression testing services make sure current
product features are still in working properly.
Communicating the importance of regression
testing to non-technical managers within your
business can be a difficult job.
Complex: One more thing to analyse here is that
as products get updated, they can grow quite
complex making the lists of tests in your
regression pack to grow to a huge amount.
Time Consuming: Regression testing is quite a
time-consuming. Regression testing often
includes running existing software tests again so
testers might not be overly enthused at having to
re-run tests.

6. Objectives Of Regression Testing:
Pitfalls Of Results Of Regression Testing
According to many organizations, the important functionality of the applications are checked once, and an
assumption is drawn that it would continue to work well until changed intentionally. But, the fact remains that
even minor modifications in code as a matter of routine are liable to have serious unanticipated side effects,
which can probably break the functionality verified earlier.
We should not become happy & get satisfied just because the system has responded as expected because
there can be every possibility of the presence of introduced bugs, which may have escaped the detection.

7. Regression Testing Can Adopt The Following
Approaches:
Delayed Sprint Approach: In this approach, the regression cycle
is normal and regression test cases that were applied for the
second sprint include the functionality stories that were a part
of the first sprint.
Delayed Week Approach: In this approach, the sprint level
regression test is not restricted to a timeline and can spill over
into the next week.
For example, if the sprint level regression test that is assumed to
be performed in Week 2 is not completed, then it can scatter
over to Week 3.
The Traditional Testing Approach: In this approach, each and
every sprint cycle is followed by sprint level regression test.
Post a few successful sprint cycles, the application goes through
one round of end-to-end regression testing.
