Cypress e2e testing with Google Maps Autocomplete

#javascript #googlecloud #programming #csharp

During my working day I encountered a problem.

I needed to be able to drive a Google Maps Autocomplete text input through Cypress Tests.

https://docs.cypress.io

https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete

As you can see above we get some suggestions as you type in the search box.

Now this is extremely easy to test manually, just jab in a place and click on a suggestion.

Cypress testing this not so much.

I scratched my head for hours trying to figure out how I could target that little suggestions list served back from Google Maps.

I went through the following google search results

The Solution

The Solution for me was something like the following




completeBranchPage: () => {
      cy.enterText(enterLocationInput, value.dumfries);
      cy.get('.pac-item', { timeout: 10000 }).should('be.visible');
      cy.enterText(enterLocationInput, '{downarrow}');
      cy.enterText(enterLocationInput, '{enter}');
      cy.get(latInput).should('have.value', value.dumfriesLat);
      cy.get(lngInput).should('have.value', value.dumfriesLong);
    }

The magic piece of the puzzle for me was making sure that the gmaps suggestion items were actually there before I tried to choose one of them.

I did this with the following line of code where .pac-item is the class of the Gmaps Autocomplete suggestions



cy.get('.pac-item', { timeout: 10000 }).should('be.visible');

I now have a passing test, WOOHOO!!!

Where's the code you jabroni?

I have created a small example repo.

You will need to add your own Google Maps API Key secret in the fashion of an environment variable or a .NET user secret.

User secret would be like the following



{
  "GmapsApiSecrets": {
    "ApiKey": "MY SUPER DOOPER SECRET KEY"
  }
}

Please feel free to fork or clone down that repo and have a play around with the code.

For anyone who has not used cypress testing in the past I'd whole heartedly recommend it. Massive shout out to our Automation Tester https://github.com/karenpetrie for introducing us to the mysterious ways of automated testing.

It is baller.

Anyways, I'm out, hope this is of help to someone
