Problem Statement
The ability to ‘Run all specs’ or ‘Run filtered specs’ will be removed in Cypress 10.0. For many of the users, the existing implementation “was broken” for them because of how cypress originally architectured supporting this feature. Cypress received feedback regarding the removal of this feature.
In this blog for demo purposes, I am using Cypress version 11.2.0
How to solve the problem
In Cypress version 11.2.0 Cypress team has introduced a feature flag experimentalRunAllSpecs that will restore the prior behavior seen in versions < 10
Steps to Implement ‘Run all specs’ feature
Below are the steps on How we can run all specs in single run
Installing Cypress
Installed Cypress version 11.2.0 using npm install cypress --save-dev
Keep feature flag disable
After installing 11.2.0 next step is to enable experimentalRunAllSpecs flag.
Let’s see when the feature flag experimentalRunAllSpecs is disabled. In the below screenshot, we can see the button to Run all specs is not displaying
Enable the feature flag
When we enable the feature flag experimentalRunAllSpecs:true we can see in the below screenshot button to Run all specs is displaying
After enabling the feature flag either we can run all .specs in a single run or can run a set of .specs
- We can run all .specs in a single run
2. We can run a SET of .spec file e.g I want to run the First Set of Spec or Second Set of Spec or Third Set of Spec See in the above screenshot
How to enable Feature Flag
In cypress.config.js set the below commandconst { defineConfig } = require(“cypress”);
module.exports = defineConfig({
e2e: {
experimentalRunAllSpecs: true,
setupNodeEvents(on, config) {
// implement node event listeners here
},
},
});
Steps to run the filtered .specs
If we want to run filtered spec we can simply search and execute the .spec from the list
Two ways of filtering the .specs file
We can run the particular .spec file from the set of specs can be seen in below screenshot
We can also search the .spec file from the Cypress runner and run the .spec file
Conclusion
The ability to ‘Run all specs’ or ‘Run filtered specs’ that was removed in the previous cypress version was re-introduced in Cypress version 11.2.0.
Using the experimentalRunAllSpecs feature flag we can restore the prior behavior and execute all/selected .specs files.
