Deliver Faster And Better Results By Using Automated Regression Testing



A growing number of software development teams today like agile software development over other development progresses. There’s no requirement to introduce Agile, but let’s talk about this anyway! We know that the agile development methodology is very adaptive in nature.

Key is that since agile development is iterative, all the features of product design are constantly revisited to make sure that change can be effected as soon as the requirement for it is identified.

It concentrates on creating a a product based on experimental feedback gathered from frequent testing by breaking down the product development procedure into shorter development periods or sprints.

What Are the Regression Testing Techniques?

·         Prioritization of test cases
·         Retest all
·        Test selection
The process of retesting all designed test cases in the set are rather cost-intensive and time-consuming as it needs much resources and effort. If the deadline is coming, then this the technique will not effect.

But instead of reusing the complete suite, it is better to use only the particular tests which can be divided into the obsolete and reusable test case. The experts will concentrate and rerun only reusable tests.

The cosmetic type of bugs or errors usually, do not affect other abilities and do not need automated regression testing.

It would be beneficial if all the tests in the test suite were rerun for each new spiral. But, due to time limitations, this is not pragmatic. Two thumb dictates for the planning of Regression Testing:

A retest matrix can be formed which is a unique tool that relates test programs to functions. The retest matrix can be created before the first testing spiral but requires to be maintained during subsequent spirals.

Useful considerations of regression testing:

1.       Client-reported errors should have high priority and must be regression tested thoroughly.
2.       Other test cases in the functional (or program unit) area where a bug is uncovered must be involved in the regression test suite.
3.       Regression tests that repeat other tests should be removed.
4.       An in-depth effort should be made to make sure that the original defect was fixed and not just the symptoms.
5.       The test that uncovered an original check should be rerun after it has been fixed.
6.       Regression testing requires occurring between releases after the initial release of the system.
7.       Regression tests are potential candidates for test automation when they are repeated over and over in every testing spiral.

Challenges of Regression Testing

Communicating Business Value:

Automated regression testing make the 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.

Executives have to see the product move forward and making a considerable time investment in regression testing to make sure existing functionality is working can be a hard sell.

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.

Concluding Definition of "Regression Testing":

It is pretty natural to have modifications in the code during software development and maintenance period. Therefore a software program that happened to execute accurately earlier may stop functioning the same way after the modifications.

Regression testing software is a software series that is created to help isolate problems that have occurred with the software on the hard drive that was working excellent, yet suddenly developed an issue.

Top Mobile automation Testing Tools In 2018

Image
Mobile phones have become an important part of our lives; be it for business or for personal use, a life without one of these devices that frequently outsmart us is impossible. Right from the first ever of its kind that hit the market, mobile phones have been reliably boosting themselves with flawless technology and unequivocal innovation. Research and Innovation team up to build a successful future only while managed adequately. Continuous Integration (CI) is one such management tool and/or aid in the mobile world wherein the developer (or coder) has to recurrently integrate copies of his work to the central server (or main database) which is frequently shared, establishing an internal ecosystem. This shared repository is checked for faults and verified successively by automated software. The software does not fundamentally remove a bug for you, yet, it can tell you from time to time the presence and significance of a bug. Therefore, continuous integration improv...

Why Do You Need a Perfect Web Application Security Testing Strategy?

Image
We live in an era where web applications have become an important part of our day to day routine due to their continuous availability and being able to access huge data on our fingertips. With this flexibility and continuous availability, there is a huge increase in the amount of data and the number of transactions on the web.  Therefore, proper security testing of web applications has become very important. From emailing to online shopping to banking, the data is stored in the web applications and all the data stored is a bait for cybercriminals to hack into the systems and get access to the information stored. Types of Web Application Security Testing Dynamic Application Security Testing (DAST): DAST is a process of testing an application which helps to look for weak links in a web application that an attacker could try to exploit. The process doesn’t require much time, and different changes can be done quickly and frequently since DAST does not require access to...

The Building Blocks of Functional Testing Automation Strategy

Image
When to begin Functional tests are described and performed when the units of the application are considered complete. If parts of the application are changed after the trial began, the test is usually considered valid and must be repeated. White box testing relaxes this demand, in that the tests are known to be affected by the change of code can be considered as still valid. When the code or environment is modified, the functional tests are replicated. Automated functional testing services enables a reliable repetition of all tests. This test phase of software development is usually shrift by developers and IT administrators. But, this testing is the only way to find out if the application is working correctly before being deployed. Functions of the Automated Testing Tools Software testing is a popular activity particularly for those who are in this sort of industry. The automation testing tools actually save them time and human effort. The tools will do ...
