            How to keep tests outside from source directory in Vite projects?
            Asked 2022-Feb-25 at 12:35

            Running npm init vue@latest with the following setup

            generates a Vitest spec file inside the src directory. I'm wondering why Cypress e2e tests have a seperate directory and Vitest unit tests are right next to the source code. Are there any reasons?

            I want to move those tests to the root directory (equal to cypress), created a vitest directory and moved to spec into it.

            The test itself passes but I think I have to change sopme configuration to exclude the tests from the build etc.

            Inside the file I changed the line "exclude": ["src/**/__tests__/*"], to "exclude": ["vitest"],.

            Is there something else I should do? Or are there any reasons to keep Vitest tests inside the source directory?



            Answered 2022-Feb-25 at 12:35

            To get the test folder outside the source folder :

            1. create a vitest folder on root dir
            2. move ./src/components/__tests__ to ./vitest/__tests__
            3. On test *.spec file, you will import components with alias @
            • import HelloWorld from '@/components/HelloWorld.vue'
            1. in
            • change "exclude": ["src/**/__tests__/*"], to "exclude": ["vitest/**/__tests__/*"],
            1. run npm run build && npm run test:unit

            Would you mind explaining why you keep the tests directory inside the vitest directory?

            You are not required to keep this folder. It's a convention, check below 👇

            If you want to put the spec file in the tests folder without a subfolder then just add to the vite.config.ts :



            Flaky cypress test with Svelte: Button is sometimes clicked, sometimes not
            Asked 2022-Feb-07 at 22:42

            I am testing my SvelteKit site with Cypress. I sometimes experience flaky tests, similar to what has been described here: In short, Cypress sometimes finds and clicks a button before the event listeners are attached - as a result, the click goes nowhere. The proposed solution is to simply re-try clicking until the appropriate listeners have been attached. That works in my case as well. However, though I do understand why this can be an issue in the example given in the blog post (it's a large calendar modal), I find it hard to justify that this issue arises when using a simple Svelte button.

            Here is a simple example of a button that reveals some content when clicked:



            Answered 2022-Feb-07 at 10:02

            SvelteKit will by default do server side rendering (SSR), which means the complete HTML is sent to the browser, including the button. That HTML then needs to be hydrated afterwards to become interactive. This means that some code runs so that Svelte connects to the HTML that already exists. Cypress is likely "too fast" here and clicks the button before that hydration step is completed, therefore nothing happens.

            It does not happen with pure Svelte because there's no SSR involved. There's a blank index.html page initially which is completely filled by Svelte's JavaScript inside the browser, so the moment the button is visible, the event listener and everything else is already initialized by Svelte.

            Comparison by steps:

            SvelteKit with SSR:

            1. Go to page X
            2. Page X is rendered on the server
            3. Page X is sent to the browser, with the complete HTML
            4. Svelte hydrates the HTML (Race condition with Cypress' click test)
            5. Completed

            Pure Svelte or SvelteKit without SSR:

            1. Go to page X
            2. Blank page is sent to the browser
            3. Svelte constructs and initializes the HTML inside the browser (No race condition with Cypress' click test)
            4. Completed



            Vue 3: Module '"../../node_modules/vue/dist/vue"' has no exported member
            Asked 2022-Jan-24 at 08:38

            After updating my npm packages, some of the imports from the 'vue' module started showing errors:

            TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'

            where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.

            What I've tried:

            • Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of TypeError: Object(...) is not a function errors in console and not rendering the app at all. In the terminal, some new warnings are introduced: "export 'X' (imported as '_X') was not found in 'vue' where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
            • Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
            • Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

            My full list of dependencies:



            Answered 2021-Aug-15 at 13:53

            That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.

            The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.

            A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.



            how can I pass the cypress.json file to cypress-tags
            Asked 2022-Jan-04 at 15:18

            I'm using cucumber preprocessor and we do not have a standard folder structure. The cypress.json file is under a e2e folder. With cypress open, it was fine because I could specify the cypress.json file location. However, with cypress-tags run, there seems to be no way to specify the location of the cypress.json file and it just fails with error:



            Answered 2021-Dec-16 at 16:38

            I also stumbled upon this problem and realized that this does not work actually.

            As a workaround I therefore moved away from the approach of using cypress-tags and instead adjusted the naming of my feature files. This allowed me to avoid the use of cypress-tags and use the normal cypress run command instead specifying config and feature files like:

            Beginning with version 9.0.0, You are now forced to declare your custom commands. See the changelog for 9.0.0 (6th bullet point under breaking changes) and see the specific information about custom commands now being typed based on the declared custom chainable here.

            Also, see this recipe on how to add custom commands and declare them properly.

            Clicking over hidden element in Cypress is not working
            Asked 2021-Oct-25 at 02:57

            I am running into this problem without finding a good solution. I tried every post that I found in Google but without success. I am isolating the problem so I can share you the exact point. I am searching an specific product in "" and I want to sort the list from the lower price to the maximum. To do so you can enter directly here and clicking over the option "Menor Precio".

            Doing manually this just works fine but with Cypress I am not being able to do that. This script just runs fine but the last step seems to have no effect.



            Answered 2021-Oct-22 at 23:49

            It looks like the click event is being added to the dropdown button late, and the click is failing.

            See When Can The Test Start? for an discussion.

            I tried to adapt the code in the article, but couldn't get it to work.

            However, adding a cy.wait() or a cy.intercept() for the last network call works.

            I have a problem when using cy.getIframeBody().find('#some-button') that the #some-button element is not yet available, because the iframe is still loading, but the body element is not empty so the .find() is triggered.

            This is the custom command to get the iframe body



            Answered 2021-Oct-06 at 13:40

            You can add an timeout and also add should('be.visible'). should assertion will make sure that till the timeout value is reached it rerties and make sure that the iframe is loaded successfully.
