The previous section describes how to build a selenium system environment, so this section explains how to start writing the first automated test script.selenium2.x the browser native API into the Webdriver API, you can directly manipulate the elements of the browser page, and even manipulate the browser itself (screenshots, window size, start, close, install plug-ins, configuration certificates, etc.), so just like the real user in the same operation

the pack takes a minimum of 1 bytes, so it is offset by 1 bytes and offset to 1. C is int,4 bytes, with a minimum value of 4 for the actual pack value, so the offset is 4. 3. The last member is padded to the actual pack value if it is smaller than the actual pack value. As in the previous structure, D is char,1 bytes and must be padded to 4 bytes, so the offset is 8. The memory of the above structure is 12 bytes, layout position: 0 1 2 3 4 5 6 7 8 9 10 11 12 Member: A B _ _ c _ _ _ D _ __ __ __

Before using the OpenSSL library, you need to detect if OpenSSL is installed, the shell window input: OpenSSL version, and after the OpenSSL installation is complete, you can write the test code through VI.In this example, we enclose the encryption, decryption code, the method is: Encodersakeyfile (...), Decodersakeyfile (...)These sample codes can be found on the web.Code:#include To generate a public private key step:OpenSSL genrsa-out test_2048.key 2048//private keyOpenSSL rsa-in test_2048.ke
