Writing tests can be a tedious and time-consuming task. TestDriver can generate tests just by exploring your app. This guide will show you how to generate tests using TestDriver.

​
Generate exploratory tests

Launch testdriverai in interactive mode with the following command: 
npx testdriverai@latest
TestDriver will boot up. 
❯ testdriverai
Howdy! I'm TestDriver v6.0.0
Ensure your website or app is visible on your test runner’s display. Then, run the generate command. 
/generate web 10
This will generate 10 tests within the testdriver/generate directory. You can change the number of tests generated by changing the number after 10. The generated tests will be in the form of a .yaml file, and you can run them using your test runner of choice (local or cloud hosted). 
> /generate web 5

Now your directory structure will look like this: 
testdriver
├── generate
│   ├── test-error-user-login.yaml
│   ├── test-locked-out-user-login.yaml
│   ├── test-navigation-to-shop-page.yaml
│   ├── test-problem-user-login.yaml
│   └── test-standard-user-login.yaml
Notice that each test file has no commands! It’s only a list of prompts. This is similar to an exploratory test. 
version: 5.3.11
steps:
  - prompt: Fill in the "Username" field with "error_user".
  - prompt: Fill in the "Password" field with "secret_password".
  - prompt: Click the "Sign in" button.
  - prompt: Assert that there are issues during checkout and an error is displayed.

​
Generate regression tests from exploratory tests

Now it’s time to generate the regression test. Run the tests with the run command and use the --write parameter: 
npx testdriverai@latest run testdriver/generate/test-error-user-login.yaml --write
When a test has no commands, TestDriver falls back to the prompt. 
> Fill in the "Username" field with "error_user".
No commands found, running exploratory
When using the --write command, TestDriver appends any generated commands to the test file. So as your test run, TestDriver will append successful commands to the YAML file and save it. 
version: 5.3.11
steps:
  - prompt: Focus the browser window.
    commands:
      - command: focus-application
        name: Google Chrome
      - command: hover-text
        text: Username
        description: username input label in the login form
        action: click
  - prompt: Fill in the "Password" field with "secret_password".
    commands:
      - command: hover-text
        text: Password
        description: password input label in the login form
        action: click
      - command: type
        text: secret_password
      - command: hover-text
        text: Password
        description: password input field in the login form
        action: click
Now the next time you run the test, TestDriver will use the commands instead of the prompt! 
npx testdriverai@latest run testdriver/generate/test-error-user-login.yaml
