# Writing tests

To write tests using Cover CLI:

* To write tests for your entire project, open Windows PowerShell (Windows) or Terminal (macOS/Linux), navigate to your project, and enter the command `dcover create`
* To restrict tests to an individual package, class, or method, specify one or more entry points on the command line using `dcover create [<entryPoint>...]` - for example, `dcover create io.diffblue.corebanking.account.Account.`
* For a quick summary of core Cover CLI commands, see [Command summary](/features/cover-cli/writing-tests/command-summary.md) . For full details - every command, every argument, every option - see [Commands & Arguments](/features/cover-cli/commands-and-arguments.md).
* In general, `dcover create` will write complete tests for your methods, classes, modules, and projects. However, Cover is not always able to create a complete test, instead it may only be able to create partial tests - see [Creating partial tests](/features/cover-cli/writing-tests/partial-tests.md).
* Once Diffblue Cover starts to run, you can cancel the operation at any point by pressing **`CTRL-C`**.
