--->", httputil.doget ("Tell Me a Joke")); - } - -}As you can see, here we send two messages to the server (that is, send a message to the robot), "Hello", "Tell me a joke". The data returned by the server is then printed out. If it prints correctly, the test is passed.Let's right-click the project name, run as, and select Android JUnit Test (Android unit testing). The printed information is then found in the Logcat, indicating that the test pass

A small partner wants to migrate servers. Because web hosts and database hosts are separated, it is necessary to test the efficiency of new environment database requests. He wrote a PHP script for testing, but the problem is that PHP has no threads, so it is equivalent to a single-thread request. Slightly unreasonable. It cannot be seen how efficient the request is in the case of multiple concurrency. Google does not see the right
At ordinary times, some performance tests are required. Simple performance tests can be replaced by AB, rather than using heavyweight tools such as LR. This article briefly introduces the use of AB tool and result analysis. Take notes for future reference. 1. Installation: to use AB, you must first install Apache, which is an Apache benchmark tool, under the Apache installation directory.2. Use: Format:./AB
