software test:
Software testing is the process of identifying the accuracy and quality of software products and services during testing. Apparently, it was born to verify that a product meets a customer's specific prerequisites and needs.
At the end of the day, determine a specific end goal and test-implement a framework or application to point out its errors, or flaws.
The responsibility of testing is to find bugs and point out problems, and provide Dev (developers) with a clue to help them correct errors according to requirements.
Goals of Software Testing
(1) Find as many errors (or bugs) as possible in a given product.
(2) Demonstrate that a given software product matches its requirement specifications.
(3) Use less cost and effort to verify the quality of the software.
(4) Generate high-quality test cases, perform effective tests, and issue correct and useful problem reports. software testing process
Software testing is usually divided into two main processes - verification & certification.
Validation is the process when your team simply needs to check that a software, system, or framework meets documented requirements.
Certification is the process your team needs to verify the correctness of your system. In the process, you'll review the product, the system, and consider what users really want and have done.
In software testing, there is a difference between defects and errors, and we should distinguish clearly to avoid misunderstanding the problem.
Software test development:
Test development engineers have two goals: quality and efficiency.
Quality is to improve product coverage to achieve higher quality;
Efficiency is to improve product testing efficiency in order to achieve faster product delivery and launch.
In order to achieve the above two points, test development engineers will use various means to achieve the above goals, including but not limited to:
(1) unit test
(2) Interface test
(3) Gray box testing (Sogou internally refers to the functional testing conducted by understanding the code implementation as gray box testing)
(4) Specific tests (performance, pressure, memory, power consumption, flow)
(5) Code walkthrough
(6) Code refactoring (Google’s test development engineers will refactor the code, which is limited to refactoring without functional development. Currently, this job responsibility has not been promoted in China.)
(7) Tool development
(8) Automation solutions...etc.
Therefore, a test development engineer is a hybrid talent: a programmer with strong coding skills who can write functional code; a strong tester who can test any product and has the ability to manage their own work and tool.
