????[?·???????? 4/14/2010] google v. microsoft?? and the dev:test ratio debate

????Google ???????????:

????Developing test strategies.

????Automating tests using test works.

????Write moderately complex code/s to test systems.

????Take responsibility for monitoring product development and usage at all levels with an eye toward improving product quality.

????May create test harnesses and infrastructure.

???????SDET?????Σ?

????Hire developers to write code to test code. Our goal is to have engineers writing robust?? reliable and repeatable tests that find issues early and cover the surface area of the component under test thoroughly.

????SDETs are in the source code for the product as much as they are working with test source and our SDETs build the work used for testing.

????Build programmatic tests that are self-verifying?? that are easily extensible and that are not simply comparing ??data in?? to ??expected out??.

????A successful SDET derives pleasure from building lasting designs?? implementing robust maintainable code?? and being a partner in the design of the components while advancing the technologies and approaches for testing software
