$ test "$variable" 强烈建议进行此种测试时用双引号将变量括住,以让 shell 识别变量(即使变量为空)。默认情况下执行的基本字符串评估和 -n 测试从功能上讲是相同的,如以下示例所示: #example1 if test -n "$1" then echo "$1" fi 执行以上例子中的代码将根据 $1 是否存在给出以下结果: $ example1 ...

This example shows how the class looks with an added setup() method that declares the path variable:Python Copy class TestIsDone: def setup(self): self.tmp_file = "/tmp/test_file" def teardown(self): if os.path.exists(self.tmp_file): os.remove(self.tmp_file) def test_yes(self)...
New environment variable LTP_VIRT_OVERRIDE was added this is meant as a quick workaround for cases where the test library cannot properly detect if system is virtualized or not see https://github.com/linux-test-project/ltp/wiki/User-Guidelines Fixed (again) timeouts in shell test library turns...

To handle this, set the MYSQLD_BOOTSTRAP environment variable to the full path name of a server that has all options enabled. mysql-test-run.pl will use that server to perform setup; it is not used to run the tests.The init_file test will fail if --init-file is disabled. This is...
The name of the variable is the name of the preset. The dict must contain all the hb parameters. If --hb-use-cloud-preset is set, then all other parameters which names start with hb- are ignored. Example of cloud_secrets.py: aws = { "hb_storage_path_prefix": "/path/inside/bucket...

✅Do:The server under test should let the test decide when to open the connection and when to close it. If the webserver do this alone automatically when its file is imported, then the test has no chance to perform important actions beforehand (e.g. change DB connection string). It al...
