Playwright

test.describe("name", () => {
  test("name", async ({ context, page, baseURL }) => {
    Setup, Visit, Act, and Assert
  });
});

Visit a page	`await page.goto("url")`
Reload page	`await page.reload()`
Take a Screenshot	`await page.screenshot({ path: filename}) await page.screenshot({ path: filename, fullPage: true}) await element.screenshot({ path: filename})`

Queries

Text Input	`await page.fill("input[name=name]", "value") await expect(page.locator("input[name=name]")).toHaveValue(regex)`
Textarea	`await page.fill("textarea[name=name]", "value") await expect(page.locator("textarea[name=name]").toHaveValue(regex)`
File Input	`await page.setInputFiles("input[name=name]", [filepath]);`
Select Input	`await page.selectOption("select[name=name]", { label: "label"})`
Checkbox and Radio	`await page.check("input[name=name]") await page.uncheck("input[name=name]") expect(await page.isChecked("input[name=name]")).toBeTruthy()`
Submit button	`await page.click("button[type=submit]")`
Everything else	`await page.locator("[data-testid=testId]") await page.locator('text="text"')`

Local and Session Storage

await context.addInitScript(arg => {
  window.localStorage.setItem("key", "value");
  window.sessionStorage.setItem("key", "value");
}, arg);

Intercepting HTTP Requests

await page.route(url, (route, request) => {
  You can also check request data: request.url() or request.postDataJSON()
  return route.fulfill({
    status: 200,
    body: data
  });
});
