| // TestContextType contains test settings and global state. Due to |
| // historic reasons, it is a mixture of items managed by the test |
| // framework itself, cloud providers and individual tests. |
| // The goal is to move anything not required by the framework |
| // into the code which uses the settings. |
| // |
| // The recommendation for those settings is: |
| // - They are stored in their own context structure or local |
| // variables. |
| // - The standard `flag` package is used to register them. |
| // The flag name should follow the pattern <part1>.<part2>....<partn> |
| // where the prefix is unlikely to conflict with other tests or |
| // standard packages and each part is in lower camel case. For |
| // example, test/e2e/storage/csi/context.go could define |
| // storage.csi.numIterations. |
| // - framework/config can be used to simplify the registration of |
| // multiple options with a single function call: |
| // var storageCSI { |
| // NumIterations `default:"1" usage:"number of iterations"` |
| // } |
| // _ config.AddOptions(&storageCSI, "storage.csi") |
| // - The direct use Viper in tests is possible, but discouraged because |
| // it only works in test suites which use Viper (which is not |
| // required) and the supported options cannot be |
| // discovered by a test suite user. |
| // |
| // Test suite authors can use framework/viper to make all command line |
| // parameters also configurable via a configuration file. |
