cypress-fail-on-network-error

> :fire: Don´t be shy and give it a try. This plugin is brand new! :fire:

The plugin observes all network requests from your configuration. Cypress test will fail when the error conditions are met. For observing console.error() please check out cypress-fail-on-console-error.

Use failOnNetworkError functions getConfig() and setConfig() with your own requirements. Detailed example implementation cypress comands & cypress test. Note that the config will be resetted to initial config between tests.
`js
const { getConfig, setConfig } = failOnNetworkError(config);

Cypress.Commands.addAll({
getConfigRequests: () => {
return cy.wrap(getConfig().requests);
},
setConfigRequests: (requests: (string | Request)[]) => {
setConfig({ ...getConfig(), requests });
},
});
`

`js
describe('example test', () => {
it('should set exclude requests', () => {
cy.setConfigRequests(['urlToExclude']);
cy.visit('url');
});
});
`

Use failOnNetworkError function waitForRequests() to wait until all pending requests are resolved. The default timeout is 10000 ms which can be changed by overriding the default value waitForRequests(5000). When reaching the timeout, Cypress test execution will continue without throwing an timeout exception.
Detailed documenation for cypress comands & cypress test.

`js
const { waitForRequests } = failOnNetworkError(config);

Cypress.Commands.addAll({
waitForRequests: () => waitForRequests(),
});
`

`js
describe('example test', () => {
it('should wait for requests to be solved', () => {
cy.visit('url');
cy.waitForRequests();
});
});
