Difference between Alpha & Beta tests

 



Alpha Testing is a type of acceptance testing; performed to identify all possible issues and bugs before releasing the final product to the end users. Alpha testing is carried out by the testers who are internal employees of the organization. The main goal is to identify the tasks that a typical user might perform and test them.

Beta Testing is performed by “real users” of the software application in “real environment” and it can be considered as a form of external User Acceptance Testing. It is the final test before shipping a product to the customers. Direct feedback from customers is a major advantage of Beta Testing. This testing helps to test products in customer’s environment.

Alpha TestingBeta Testing
Alpha testing performed by Testers who are usually internal employees of the organizationBeta testing is performed by Clients or End Users who are not employees of the organization
Alpha Testing performed at developer’s siteBeta testing is performed at a client location or end user of the product
Reliability and Security Testing are not performed in-depth Alpha TestingReliability, Security, Robustness are checked during Beta Testing
Alpha testing involves both the white box and black box techniquesBeta Testing typically uses Black Box Testing
Alpha testing requires a lab environment or testing environmentBeta testing doesn’t require any lab environment or testing environment. The software is made available to the public and is said to be real time environment
Long execution cycle may be required for Alpha testingOnly a few weeks of execution are required for Beta testing
Critical issues or fixes can be addressed by developers immediately in Alpha testingMost of the issues or feedback is collected from Beta testing will be implemented in future versions of the product
Alpha testing is to ensure the quality of the product before moving to Beta testingBeta testing also concentrates on the quality of the product, but gathers users input on the product and ensures that the product is ready for real time users

What are the different types of Non-Functional Tests

Image
Non Functional Testing Non-Functional Testing  is defined as a type of Software testing to check non-functional aspects (performance, usability, reliability, etc) of a software application. Following are the most common  Types of Non Functional  Testing: Performance Testing Load Testing Failover Testing Compatibility Testing Usability Testing Stress Testing Maintainability Testing Scalability Testing Volume Testing Security Testing Disaster Recovery Testing Compliance Testing Portability Testing Efficiency Testing Reliability Testing Baseline Testing Endurance Testing Documentation Testing Recovery Testing Internationalization Testing Localization Testing 1) Security: The parameter defines how a system is safeguarded against deliberate and sudden attacks from internal and external sources. This is tested via Security Testing. 2) Reliability: The extent to which any software system continuously performs the specified functions without failure. This is tested by R...

What is CI, CD & CT?

Image
Continuous Integration (CT), continuous Testing (CT) and continuous Delivery (CD) accelerate the code release process and are thus crucial to DevOps. These processes are often referred to as a  CI/CD pipeline  or a  DevOps pipeline. Continuous integration.  In the CI stage, developers write a feature, update or fix, then commit the code to a central code repository. Organizations often use  version control tools  like GitHub and Atlassian Bitbucket. These tools enable developers to write or modify code without interrupting another developer's progress. Once the code commits to the repo, Continuous Testing (CT) begins to  shine. In the initial stage of the pipeline, static code analysis can check for syntax issues and common vulnerabilities. Use plugins in the CI server to configure static code analysis with a tool.  Static code analysis is an initial test of the code. If the code passes, the unit test stage comes next, unless these tests wer...

How to push changes to Git Hub using GIT GUI?

Image
Getting started with Git GUI Step 1: Create Remote Repository Now, we need a Git repository, and we’ll create a new remote repository on Github. Step 2: Create a Local Repository For creating a local repository: in our Git GUI, click on  “Create New Repository” . Select the location you wish to store your repository in. It is important to note that the selected repository location MUST NOT  exist. In order for this new repository to be initialized, you must first create a file, any file, in your local repo.Then, you must Commit and Push to the remote Git repository location. Step 3: Clone a Remote Repository to a Local Repository In order to clone a repository, click on the “ Clone Existing Repository ” link in the Git GUI window. An existing repository is one that is already initialized and/or has commits pushed to it. Note:  In the Source Location field, fill in the Git remote repository location. The target directory works as same in the case of creating a local reposi...
