cypress-gmail-tester

Use Cypress E2E tests to check Gmail-based inboxes using the gmail-tester library.

Usage

1. Install using npm:

npm install --save gmail-tester

2. Modify cypress.config.json

Create a task and call it gmail:get-messages in cypress.config.json, as shown here:

const { defineConfig } = require("cypress");
const gmailTester = require("gmail-tester");
const path = require("path");

module.exports = defineConfig({
  e2e: {
    setupNodeEvents(on, config) {
      on("task", {
        "gmail:get-messages": async (args) => {
          const messages = await gmailTester.get_messages(
            path.resolve(__dirname, "credentials.json"),
            path.resolve(__dirname, "token.json"),
            args.options
          );
          return messages;
        }
      });
    },
  },
});

Make sure credentials.json and token.json file are located in cypress root folder (in the same location as cypress.config.json) .More information on credentials.json and token.json can be found here.

3. Call the task within any spec:

/// <reference types="Cypress" />

describe("Email assertion:", () => {
  it("Using gmail_tester.get_messages(), look for an email with specific subject and link in email body", function () {
    // debugger; //Uncomment for debugger to work...
    cy.task("gmail:get-messages", {
      options: {
        from: "[email protected]",
        subject: "Ubisoft Password Change Request",
        include_body: true,
        before: new Date(2019, 8, 24, 12, 31, 13), // Before September 24rd, 2019 12:31:13
        after: new Date(2019, 7, 23), // After August 23, 2019
      },
    }).then((emails) => {
      assert.isAtLeast(
        emails.length,
        1,
        "Expected to find at least one email, but none were found!"
      );
      const body = emails[0].body.html;
      assert.isTrue(
        body.indexOf(
          "https://account-uplay.ubi.com/en-GB/action/change-password?genomeid="
        ) >= 0,
        "Found reset link!"
      );
    });
  });
});
