Regression Testing

Question

what are Regression testing?

Answer 1

Regression testing is a sort of software testing used to check for unexpected consequences of program modifications. Regression testing is thus used to ensure that modifications to the software (such as bug patches or new features) do not result in the introduction of any fresh mistakes or issues.

Regression testing is typically carried out by manually running a set of tests that have already been run on the program and comparing the outcomes to those of fresh runs of those tests. If any discrepancies are discovered, it means that the software has undergone a modification that has rendered it broken (or "regressing") from its previously functioning condition.

Businesses must regularly perform regression testing on their products and services to make sure they are operating as intended. Businesses can prevent concerns from developing into larger ones down the road by conducting tests on a regular basis.

Regression testing can also assist companies in enhancing their general quality control procedures. Businesses can ultimately save a great deal of time and money by spotting and resolving possible issues early on.

Regression testing is fundamental to any quality assurance procedure. By spotting potential problems early on, businesses can save a significant amount of time and money in the long run. Additionally, firms can guarantee that their products are of high quality by enhancing their general quality control procedures.

Regression testing involves retesting a system or application after modifications have been made to make sure no bugs were added or made to recur. All impacted software, including code, applications, databases, and interfaces, must be tested in order to execute regression testing effectively.

Regression testing typically involves the following four steps:

Identify what needs to be tested: taking into account both what has changed and how those changes have affected different parts of the system.
Pick the right test cases: Tests that make use of the modified functionality should be chosen.
Carry out the test cases: The test cases are carried out, and the outcomes are compared to what is anticipated.
Examine the findings: Any differences between the results as received and those anticipated must be looked into. To ascertain the root of the issue, this may entail reviewing logs, code, or other data.

Regression testing, a critical step in the software development process, ensures that changes made to a system do not break existing functionality or cause new problems. Regression testing can be carried out properly and efficiently by following these four stages.

Answer 3

Regression testing can be done with a variety of tools, including standalone ones and those that come included with well-known software development frameworks. Among the more well-liked choices are:

JUnit: JUnit is a well-liked Java unit testing framework that supports regression testing. Simply create a new test suite and include your old tests in it to use JUnit for regression testing. Then, as a part of your automated build process, run the suite.
NUnit: Similar to JUnit, NUnit is the.NET equivalent of JUnit. Simply add your current tests to a new test suite, which you can then execute as part of your automated build process.
Selenium: A programme for automating web browsers that can be used to check for regression in web applications To use Selenium for regression testing, just use the Selenium IDE plugin for Firefox to record your test cases, then execute the tests as part of your automated build process.
Rational Functional Tester: it is a commercial software programme from IBM that was created exclusively for regression testing. Various programmes, including desktop and web apps, can be tested with it.
QuickTest Professional: Another HP commercial programme made exclusively for regression testing, QuickTest Professional. It can also be utilised to evaluate a variety of applications.

Answer 4

When selecting a regression testing company for yourself, keep the following in mind:

Make sure the organization has a lot of expertise performing the testing you need.
Inquire about the company's process and whether it can modify its strategy to match your unique needs.
Make sure the company has a good standing and is known for providing services of the highest calibre. Obtain quotations from several businesses, evaluate the costs, and pick the solution that best suits your demands.
Request an example of how they would test your particular application or website using their testing tools.
Learn what kind of reporting the organisation offers and how frequently they will produce.
