Cypress Protocol Buffers

Encode a fixture with Protocol Buffers

Use this plugin to encode a Cypress fixture with Protocol Buffers.

Installation

npm i -D cypress-protobuf
# or
yarn add -D cypress-protobuf

then open your cypress/plugins/index.js file and register a new task

module.exports = on => {
  on("task", {
    protobufEncode: require("cypress-protobuf"),
  });
};

How to use it

To encode with Protocol Buffers a fixture

cy.fixture("FIXTURE_NAME.json+")
  .then(json => {
    cy.task("protobufEncode", {
      fixtureBody: json, // the fixture body
      message: "MESSAGE_NAME", // the protobuf message to use
      protoFilePath: "./public/example.proto", // the path (starting from your project directory) to the .profo file
    })
  .then(encodedJson => {
    // 🎉 `encodedJson` contains the encoded fixture
    cy.route({
      headers: {
        "content-type": "application/octet-stream"
      },
      response: encodedJson,
      url: 'API_URL'
    }).as("FIXTURE_NAME");
  });
});

and in your test you will wait for the request as usual

cy.wait("@YOUR_FIXTURE_NAME");

Take a look at the example test source code.

Tips

• the plugin saves the last protoFilePath so you can avoid to pass it every time. You can even set it at the beginning of your test suite

before(() => {
  cy.task("protobufEncode", {
    protoFilePath: "./public/escrow/ui.proto"
  });
});
