To answer this question, you need to understand the concept of alpha testing. Let's go through each option to understand why it is correct or incorrect:
Option A) Post-release testing by end user representatives at the developer’s site. - This option is incorrect. Alpha testing is performed before the release of the software, not after.
Option B) The first testing that is performed. - This option is incorrect. Alpha testing is not always the first testing that is performed. There are other types of testing, such as unit testing and integration testing, that are typically performed before alpha testing.
Option C) Pre-release testing by end user representatives at the developer’s site. - This option is correct. Alpha testing is a type of pre-release testing where end user representatives test the software at the developer's site. This testing helps to identify any issues or bugs before the software is released to the general public.
Option D) Pre-release testing by end user representatives at their sites. - This option is incorrect. Alpha testing is typically conducted at the developer's site, not at the end user representatives' sites.
The correct answer is C) Pre-release testing by end user representatives at the developer’s site. This option is correct because alpha testing is a type of pre-release testing performed by end user representatives at the developer's site.
