Alpha, Beta & Gamma Testing!!!
In this article, let us see Alpha , Beta & Gamma Testing.
1. Alpha Testing :
It is a type of testing done by tester before releasing product or software to the market.
There are three types of Alpha testing:
1. Pre-Alpha Testing : Testing all the features at the high level & check whether the product is eligible for next level of testing.
2. Alpha Testing : Thorough & Rigorous Testing like Functional Testing , Integration Testing & System testing.
3. Post-Alpha Testing : Requirements will be freezed, developers will be fixing the defects & Tester will be testing the defects.
2. Beta Testing :
It is a type of testing done by the Tester or end users or customers once after software is released to the market.
3. Gamma Testing :
It is the third stage of software testing which is done by sometimes after Beta Testing & before commercial release of software to the customer.

Difference between Retesting and Regression Testing!!!!
In this article will see the difference between Retesting and Regression Testing.
First let us see the definition.
1. Retesting:
When developer give the build, check whether the defect is fixed or not is called as Retesting.
It is also called as Confirmation Testing.
2. Regression Testing:
Testing the unchanged feature or re-execution of same test cases to confirm that adding feature,
modifying feature, deleting feature is not impacting old features is called as Regression Testing.
Below are the differences:
|
Retesting |
Regression Testing |
|
Retesting is done for failed test cases. |
Regression testing is done for passed test cases. |
|
It is planned testing. |
It is generic testing. |
|
Here, we can't go for automation. |
Here, we can go for automation. |
|
It takes highest priority. |
Takes less priority compared to retesting. |

Verification & Validation!
Verification & Validation...🤔
What they really means?
Verification: Verifying/Testing Customer Requirement Specification, System Requirement Specification , High Level Design, Low Level Design and also check whether it is according to the requirement or not, is called as Verification. It is done before software is developed.
Here we ensure that "Are we building product right/software right/system right".
Validation: Testing the functionality of an application by executing test cases is called as Validation. It is done once the software is developed.
Here we ensure that "Are we building right product/right software/right system".

Different Domain Knowledge for Testers!!!
We have many domains like Automobile, Ecommerce, banking etc. As we testers should understand basics of domain which we work and also others. I was searching how to get that and found few links created by Inder P Singh which helped me to get overview of ecommerce, Banking, automobile industry.

Below are the links to watch:
For Banking Domain knowledge: Banking Domain Knowledge
For Automobile Domain knowledge : Automobile Domain Knowledge
For Ecommerce Domain knowledge: Ecommerce Domain Knowledge
For Telecom Domain knowledge : Telecom Domain Knowledge
I know actual domain and application knowledge will be getting when we work and understand. Hope it helps someone who wants to know basics of different Domain knowledge as we all will not get chance to work on all.
Thanks for reading, hope you liked it.

Types of defects!!!!
As we all test the software in order to find defects, we also need to know types of defects.
There are many types of defects in general.
1.Functionality defects
2.Compatibility defects
3. Cosmetic defects
4. Performance defects
5. Security defects
6. Database defects
7. Wrong implementation defects
8. Missing implementation defects
9. Blocker defects
10.Major defects
11.Critical defects
12.Minor defects
These are few of the types of defects which I came across.

Test Scenario & Test Case!!!!!
Test Scenario and Test Case are the most important and commonly used terms in Software Testing.
In simple terms and sentences we see both the terms as,
What is Test Scenario?
Test Scenario is a high level documentation of all the customer business work flows according to the requirement. By looking into the test scenario we can not test any project or application until and unless we have very good project/product knowledge.
Example : For Whatsapp application, Open Whatsapp, click on Chats, Open a chat, Click on Search and enter any letters, it should be highlighted.
What is Test Case?
Test Case is a detailed documentation of scenario which helps to Tester to test the application. By looking into testcases, we can test any project or any application without having product knowledge because it will be in detail.
Example: For the above scenario,
Step:1: Open Whatsapp
Step:2: Click on Chats
Step:3: Open a Chat
Step:4: Enter letter 'A'
Step:5: Check whether the text containing 'A' are highlighted or not.
While writing test cases, all the details will be provided like test data, expected result to compare and step by step test steps.

Software Test Life Cycle!!!!
Software Testing mainly focuses whether the developed
system meets the customer/stakeholder’s expectations. Software Testing itself
has many phases and it is called as STLC. STLC is a part of Software Development
Life Cycle. SDLC has many phases and STLC is a part of it.
Below flow diagram shows the different phases of STLC:
Requirements is the input to STLC. Software Testing starts with Requirements, firstly Requirements will be studied by entire team that is called as System Study. After the first two phases, Test Plan will be created to understand the scope of Testing. Once after Test Plan is created, detailed Test cases will be written / created. Traceability Matrix will be created to ensure each requirement is covered with the test cases. Test Execution and Defect Tracking will be done if there are any defects. Once all the test cases are executed and finished. Then Test Execution report will be created and retrospect meeting will be conducted to discuss about what went well and what didn’t go well.We will see all the phases in detail below:
1.Requirements:
The very first is Requirements and it is the input for Testing. It is the phase where Software Testing starts. Requirements will be discussed with the entire team.
2. System Study:
The requirements given in first phase will be deeply studied and process starts with writing Test Plan.
3.Write Test Plan:
Test Plan is a document which derives all the Testing
activities of the project. All the future Testing activities will be planned
and document in this and it is known as Test Plan.
It contains below information usually:
• Number of Testers needed.
• Who should Test which module and which
feature.
• Which will be the Defect Tracking tool.
• Start and End Dates of writing Test Cases and
Execution planned dates.
• Scope of Testing
4.Write Test Cases:
In this phase,
Test Cases will be created. These Test Cases will be reviewed and after all
review comments are updated and once the test cases are approved, they will be
stored in a Test Case repository.
5.Traceability Matrix:
Traceability matrix is a document which ensures that every
requirement has a test case. Test cases are written by referring to the
requirements and test cases are executed by using them.
If any requirement is missed and test cases are not created
for that particular requirement, then testing will not be done for that module
/feature. To make sure that all the requirements are having at least one test
case.
6.Defect Tracking:
Bug/ Defect found by QA team is sent to the development
team. This should be followed up by QA team until it is fixed and if it is
really fixed then need to do Retesting and also Regression Testing based on the
need and defect should be closed.
7.Test Execution Report:
It is a report generated once Testing is completed. Usually
it is prepared after every Test Cycle and sent to Development team, Testing
team, Management team and also sometimes Customer.
The last Test Execution report will be sent to customer and this means that project is over.It contains below information usually:
•
List of Bugs
•
Summary of Test Cases passed and failed.
•
Summary of Deferred Test Cases
8.Retrospect Meeting:
It is also called as Post Mortem meeting or Project Closure Meeting. It is conducted to discuss the achievements and mistakes in the project. “What went well” and What didn’t go well” will be discussed and document in Quality Management System under Retrospect folder.
These are the various phases of STLC generally.

SEVERITY & PRIORITY OF A BUG😎!!!
Severity and Priority of a Bug are the mandatory fields of a Bug Report because these two fields helps to decide how quickly a bug should be fixed.
What is Severity?
Severity is the impact of the bug on customer's business and tells how severe the bug is and the impact of the bug.
What is Priority?
Priority defines how soon the defect should be fixed.It defines the importance of the bug.
Generally, Severity is assigned by Tester/Test Lead and priority is assigned by Developer/Project Lead.It requires whole team to decide. Development team will fix the High Priority Bugs first rather than high Severity.
Examples of Different Combinations:
High Priority & Low Severity: Logo of the company or brand ,it won't cause lot of damage but need to be fixed as soon as possible.
High Priority & High Severity: In an Ecommerce website, 'Submit' button is not working.When user enters all the information and clicks on 'Submit' button , it throws error.
Low Priority & Low Severity: Spelling mistakes , a page is taking more time to load than usual.
Low Priority & High Severity: Browser compatibility issues
These are only the examples, in real time whole team will decide these two fields as per the application and business flows.
Happy Software Testing!!!!!!
