# stress-test-01

C# .NET console app that launches 20 Playwright Chromium instances, navigates to the deployed URL, and clicks a button every 200ms.

## Defaults

- URL: prompted from user input every run
- Instances: `20`
- Interval: `200` ms
- Button selector: `button:visible` (first match)
- Headless: `true`

## Run

```bash
cd Testing/stress-test-01
dotnet restore
dotnet build
./bin/Debug/net10.0/.playwright/node/linux-x64/node ./bin/Debug/net10.0/.playwright/package/cli.js install chromium
dotnet run
```

PowerShell alternative:

```bash
pwsh bin/Debug/net10.0/playwright.ps1 install chromium
```

The app will prompt:

```text
Enter target URL:
```

## Optional overrides

Use either environment variables or CLI args:

- `INSTANCE_COUNT` or `--instances=<value>`
- `CLICK_INTERVAL_MS` or `--intervalms=<value>`
- `BUTTON_SELECTOR` or `--selector=<value>`
- `HEADLESS` or `--headless=<true|false>`

Example:

```bash
INSTANCE_COUNT=20 CLICK_INTERVAL_MS=200 dotnet run
```
