Software applications go through various stages of development, from initial idea to the final product. Alpha testing is the first stage of acceptance testing. Alpha testing is carried out only by its developers as opposed to external user-testers.
Alpha testing is carried out when the code is roughly ready. The software programmers have made initial checks to ensure the specifications have been met. The code then goes to a testing team that have the task of formally checking the code.
