Difference between Alpha and Beta Testing

-

  • Alpha Testing
  • Beta Testing
- Alpha testing performed by Testers who are usually internal employees of the organization

- Beta testing is performed by Clients or End Users who are not employees of the organization

- Alpha Testing performed at developer's site

- Beta testing is performed at client location or end user of the product

- Reliability and security testing are not performed  in-depth Alpha Testing

- Reliability, Security, Robustness are checked during Beta Testing

- Alpha testing involves both the white box and black box techniques

- Beta Testing typically uses black box testing

- Alpha testing requires lab environment or testing environment

- Beta testing doesn't require any lab environment or testing environment. Software is made available to the public and  is said to be real time environment

- Long execution cycle may be required for Alpha testing
Only few weeks of execution are required for Beta testing
Critical issues or fixes can be addressed by developers immediately in Alpha testing
Most 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 testing
Beta testing also concentrates on quality of the product, but gathers users input on the product and ensures that the product is ready for real time users.

Compare a range of Hardware and Software Troubleshooting Tools

H ARDWARE TESTING TOOLS  Hardware testing tools are usually for testing a computer while it off, and to diagnose/fix more complex hardware problems. These tools I am about to compare all have different uses and so are hard to compare in this format MULTI-METER  A multi-meter is used to measure the electrical properties flowing through a cable, such as amperage, voltage and electrical resistance. It can measure other electrical variables as well, but these are mostly not used for computer maintenance purposes.  The multi-meter is generally just used to narrow down the problem to the power supply. However it can also be used to check if the power source the computer’s power supply is connected to, is also running within tolerances. ETHERNET CABLE TESTER  An ethernet cable tester is used to test an ethernet cable’s ability to send/receive data. The tester will usually send some test data or power to the other end, which the tester then checks to see if it rec

What is System testing

-
Image
System testing of software or hardware is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. In system testing the behavior of whole system/product is tested as defined by the scope of the development project or product. It may include tests based on risks and/or requirement specifications, business process, use cases, or other high level descriptions of system behavior, interactions with the operating systems, and system resources. System testing is most often the final test to verify that the system to be delivered meets the specification and its purpose. System testing is carried out by specialists testers or independent testers. System testing should investigate both functional and non-functional requirements of the testing. Types of System Testing Usability Testing -     Usability testing mainly focuses on the user's ease to use the application, flexibility in han

What is Boundary value analysis in software testing?

-
Image
Boundary value analysis  is based on testing at the boundaries between partitions. Here we have both valid boundaries (in the valid partitions) and invalid boundaries (in the invalid partitions). As an example, consider a printer that has an input option of the number of copies to be made, from 1 to 99. To apply boundary value analysis, we will take the minimum and maximum (boundary) values from the valid partition (1 and 99 in this case) together with the first or last value respectively in each of the invalid partitions adjacent to the valid partition (0 and 100 in this case). In this example we would have three equivalence partitioning tests (one from each of the three partitions) and four boundary value tests.  While testing why it is important to do both equivalence partitioning and boundary value analysis? because every boundary is in some partition, if you did only boundary value analysis you would also have tested every equivalence partition. However, this approach may
