Alpha Testing: A crucial “first look” at the initial design, usually done in-house. The results of the Alpha test either confirm that the product performs according to its specifications or uncovers areas where the product is deficient. The testing environment should try to simulate the conditions under which the product will actually be used as closely as possible.
阿尔法测试:对原始设计的首次重要检查，通常在公司内完成。阿尔法测试的结果可证明产品是否按照规格设计，也可发现产品不足之处。测试环境应当尽可能模仿产品将来的实际使用环境。
