IntelliJ IDEA Test Coverage window doesn't show



I'm using Spring Boot project with the last version of IntelliJ IDEA (2018.2.1 Ultimate Edition).



When I run all my test with coverage the Coverage window doesn't show, and there's no percentage beside my main classes.



I've tried enabling the coverage window by going to View -> Tool Windows -> Coverage, but the coverage tab is disabled (not clickable).


View -> Tool Windows -> Coverage

If I remember correctly the coverage was working fine before I update IntelliJ. Is that a bug with the last version ?



Edit

the coverage plugin is already installed

Try to reinstall Intellij IDEA. When installing, he asks about install the "Coverage" plugin.

If it's a matter of the plugin not being installed, you don't have to reinstall the IDE to solve it...just install the plugin.

I ran tests with coverage of the SpringBoot app with IntelliJ IDEA 2018.2 (Build #IU-182.3684.101, built on July 24, 2018) and then with IntelliJ IDEA 2018.2.1 (Build #IU-182.3911.36, built on August 6, 2018) Coverage window showed in both cases. So it doesn't look like an update issue.

Potentially the Coverage plugin is installed but disabled on your machine e.g. IntelliJ wasn't restarted after plugin was enabled. Try restarting after double checking that Coverage plugin is enabled. As per IntelliJ Code Coverage docs:



Make sure the Code Coverage plugin is enabled. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins settings page as described in Managing Plugins. If the plugin is disabled, the code coverage tabs will not be visible in the run/debug configuration dialogs.



Try opening Settings > Build, Execution, Deployment > Coverage and check the "Activate Coverage View" checkbox. After that run another test with Coverage.





Thanks for your answer, i checked all what's you say but nothing works.

@K.Ayoub are you running IntelliJ on some kind of ancient JDK 6 or beading edge JDK 10/11?

I'm running Intellij on JDK 10

@K.Ayoub coverage is based on bytecode instrumentation or other low level JDK features. Try downgrading to 8 or 9 and see if it helps with this particular plugin.

It's not a problem with JDK or latest version of IntelliJ.



Here is the step you follow and see the coverage window. Run project with coverage, sometimes coverage window not shown if you are unable to see coverage window then



After this, your coverage window is shown.



Still, if you are unable to see coverage window then please double check is coverage view enable or not follow these steps:



Again follow the above step run with coverage, press shift+f9 etc.



Hope this help.





The first radio box already selected, the shift+f9 didn't help.

After running with coverage, press on debugging then it'll work.

Try and go to


Run-->edit configurations-->select code coverage ( then you can select IDEA/EMMA/...)





Intellij Idea is selected by default.

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right.

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
