What do you mean by pesticide paradox?  What you can do to overcome it.

Answer»

The pesticide paradox is basically a phenomenon where the more one tests the software, the more it becomes immune to its tests. To overcome this, testers should always find new strategies, approaches, and test cases, so that they can identify bugs and resolve them. The following methods can be used to prevent the pesticide paradox:


  • Create a new set of test cases for different components of the software.

  • Adding new test cases to the existing test cases.

The use of these methods can lead to finding more defects in the areas where defect levels have declined.

Explain different stages of the defect life cycle.

Answer»

The defect life cycle consists of the following stages:



  • New: Potential defect that hasn't been validated.


  • Assigned: Assigned to a team for resolution, but not yet resolved.


  • Active: Developers are currently investigating the defect and addressing it. Deferred or Rejected are the two possible outcomes at this stage.


  • Test: The defect has been fixed and can be tested.


  • Verified: The defect has been retested and the results have been verified by QA.


  • Closed: Defect in its final state, which can be closed after retesting by QA or when considered duplicate or not a defect.


  • Reopened: QA reopens/reactivates a defect when it has not been fixed.


  • Deferred: A defect that can't be addressed in the current cycle is deferred to a future release.


  • Rejected: There are three common reasons for rejecting a defect: duplicate, not a defect, and not reproducible.

What is the difference between Regression and Retesting?

Answer»


  • Regression Testing: Regression testing, also known as generic testing, revolves around re-running functional and non-functional tests. It is especially done to ensure whether previously developed and tested software still performs the same after a change or not. It can be performed either manually or using automated tests


  • Re-testing: Re-testing, also known as planned testing, is used for specific bugs after it has been fixed by the developers. Re-testing is performed to check the scenario under the same environmental conditions after detection has been fixed. 

Regression vs Retesting

RegressionRetesting 
It is performed to make sure that the changes haven't affected the unchanged part. This is done to ensure that the test cases which were filed during the last execution are passed after the detected bugs have been fixed by developers. 
It is not carried out to fix specific detects. Usually, it is based on fixing defects. 
It is only the previous version functionality centric. It is current or previous version functionality centric.
It can be performed parallel with retesting. It is needed to perform before regression testing. 
It does not include the verification of bugs. It includes the verification of bugs. 
In this type of testing, test cases can be automated and the testing style is generic.In this type of testing, test cases cannot be automated and the testing is done in a planned manner. 
It is only used for passed test cases. It is only used for failed test cases.

Explain RTM (Requirement Traceability Matrix).

Answer»

The RTM (Requirements Traceability Matrix) is defined as a tool used to identify and track the requirements and deliverables of a project. This is accomplished by establishing a thread for each component.  In addition, it manages the overall requirements of the project. There is nothing complicated about this method, and anyone can do it.

RTMs come in many forms. A test matrix, for example, proves that tests were conducted. Additionally, it can be used during the software development process to identify issues and requirements.

State difference between alpha testing and beta testing.

Answer»

Alpha and beta testing differ in the following ways:

Alpha TestingBeta Testing
During this type of testing, bugs are identified before the product is released to users. An example of a user acceptance test is Alpha Testing. The test is conducted by real users of the software application in a real environment. An example of a User Acceptance Test is beta testing. 
Both white box and black box testing are involved in Alpha testing.A black-box testing is commonly used in beta testing.
In most cases, alpha testing is done by internal testers within an organization.Clients who are not affiliated with the organization perform beta testing.
As the activities are performed on the developer's site, they can be controlled.Because activities are performed in the real world, in the end, the user's environment, cannot be controlled. 
Alpha testing does not include robustness and security tests.Beta testing includes robustness and security tests.
The quality evaluation is the main objective.Customer satisfaction is the main objective.
Alpha testing allows developers to quickly address critical issues.Most of the issues or feedback gathered during beta testing will be incorporated into future versions.

What is the term ‘quality’ mean when testing?

Answer»

In general, quality software is usually free of bugs, is delivered on time and on budget, meets most of the requirements and/or expectations, and is easy to maintain. However, 'quality' is a subjective concept. A lot depends on whom the "customer" is as well as the extent to which they are influential in general. For instance, a user may define quality as user-friendliness and bug-free while an accounting department might define quality as profits.

State difference between static and dynamic testing.

Answer»

Static and Dynamic testing differ in the following ways:

Static TestingDynamic Testing
In static testing, software applications are tested without executing any code at the very beginning of the SDLC.The test checks software functionality, memory/CPU usage, and system performance at the end of the development cycle.
It is performed during the verification stage.It is performed during the validation stage.
This is performed prior to the deployment of the code.Following the deployment of the code, dynamic testing is performed.
A static test prevents defects from occurring.In dynamic testing, defects are detected and fixed.
A walkthrough, technical review, and inspection are all part of this process.Functional and non-functional testing is involved in this process.
Errors are found early in the development process, thereby improving the quality of software applications.The main objective is to ensure that the software product meets the business requirements.

State the difference between bug leakage and bug release.

Answer»

Bug leakage and bug release differ in the following ways:

Bug LeakageBug Release 
Bug leakage refers to a defect that exists during testing yet is not discovered by the tester but is eventually discovered by the end-user.When a piece of software is released with a known bug(s) or defect(s), it is termed a bug release.
It is usually a high priority/severity bug.It is not a high priority/severity bug.
The bugs need to be addressed immediately and resolved as soon as possible.Software companies do this when they can afford to release software with bugs, but cannot afford to fix them in that version.

What white-box testing?

Answer»

White-box testing is an alternative to black-box testing that involves viewing the system as a transparent box. It is possible for the testers to observe the internal implementation of the system, which helps them conduct the test. In most cases, white-box testing is performed by the software developers during the development process.

It is also referred to as closed-box testing.

In white-box testing, we assume that the tester has some programming knowledge. The test covers all possible branches a program could follow in a running system. The more you know about the inside of a system, such as its source code and implementation details, the more thoroughly you can test it.

Explain bugs, defects, and errors.

Answer»


  • Error: The error occurs when there is a programming mistake in the code that prevents the program from executing or compiling.


  • Defect: A defect is any variation between the actual result and the expected result determined by a tester or developer. Defects are typically detected after the product enters production and are resolved only during the development phase.


  • Bug: A software bug is detected during the testing phase as a fault or mismatch. This affects the functionality and performance of the software.
