The objective here is to have the option to set a limit to the maximum number of skips possible without answering a question.

Write tests for new APIs

The present field text needs to be called description, also there needs to be another field called name. This name would help identify the question easily and would be useful while generating a report for how the candidate did.

If you view report for a candidate and come back to the candidate list page corresponding to a quiz, the candidate whose report was viewed recently should be highlighted?

The quiz duration and any durations for that matter should be sent in a format understandable by the backend.

This https://github.com/icholy/Duration.js/tree/golang_compatible should do the job and would save you some time at the cost of adding a dependency. We can start with this and replace this later.

1. Add/Edit question, spelling of Positive. Also call it Positive Score maybe.
2. Pagination, spelling of questions in No more questions.

Right now it allows dates before today too.

In the case that the client crashed or the candidate closed the browser and tries to restart the quiz, /validate API would return quiz_started as true. In this case, instructions screen shouldn't be shown, next question should be fetched and shown.

Add Invite page has validations but not update invite. I could update invite information by setting everything to empty. This is the same as the question add/edit. How come pages which Add and Edit have different behavior in terms of validations?

In case the server crashes, Ping API won't be respond. We should stop the user and let him know that something is wrong and that he should contact Dgraph.

I clicked on a question to see details and it took me to login page. That's weird.

Removing the question associated with the particular is working. But need to allow admin to add new questions to it.

The objective here is to see if we can vary the width of different boxes(questions and scoring) to display the information in the best possible manner.

If a user is logged into the Admin panel and tries to take the quiz using the link, wrong routes are hit and we get Something Went Wrong error while taking the quiz.

To reproduce clear all cache from the browser. Log into gru.dgraph.io and go to Add question. You can't type in the Add Question box. After you refresh the page you can but not before that. Possibly some js that is not loaded?

From candidate invite add/edit view, we should allow only one quiz to be selected.
If same candidate has to be invited to multiple quizzes, we can create multiple invites and shouldn't do this within the same invite for now.

Candidate Edit API should send non-empty old_quiz_id and quiz_id only if quiz which the candidate is invited to is changed. If quiz was not changed, then both should be empty.

1. /validate would also return a duration along with the token on successful authentication. This duration should be shown on the instructions screen and the initial time left should be the same as this.
2. /ping needs to be called on every 5 sec in a background function after the quiz starts and until it is finished. It will return the time_left, this has to be synchronized with the total time left for the quiz.
3. There should also be a time taken for each question which can be managed on the client side and should be reset on showing a new question.

Document APIs used for questions/tags.

I logged the aid received. For questions with multiple answers, it is empty. It should be a comma separated string of answer id's. Please check.

Add ability to end test if score goes below a certain value. This value can be part of config which can be shared during the authenticate call.

Earlier, question had a validation that it should have at least one tag. That seems to have been removed. A question can now be saved (while editing only) without any tags. Moreover, the option to edit a question which was saved without any tags seems to be missing.

The test should be ended when ping returns timeLeft < 0. Right now the timeLeft becomes negative and the test continues. 👎

Maybe have a cutoff score as part of config and tell them that they failed screening if they don't cross the score.

When I am not logged in and I go to gru.dgraph.io, before the login screen is shown a page with a blue navbar is rendered and then the login page is rendered.

When I am already logged in, the login page is rendered and then within a second the dashboard is rendered which again produces a flicker effect.

The correct page is rendered very quickly but still it makes for a weird output so we should correct this.

If while taking the quiz, the quiz page moves out of focus say 3 times, we can end the quiz.

Provide UI to edit quiz infromation

Maybe have a build process which concatenates these files so that there are less network calls and the assets load faster?

Time taken on final screen shouldn't just be the time taken for the final question. It should be the total time taken in the test. You could potentially store the duration of the quiz the first time the validate API call is made and use that to calculate the time left.

Also, we don't need to show timeleft.

The objective here is to randomize the order of options for a question before sending it to a candidate. We already randomize the order of questions. Something similar for answer options should work.

I had to modify the server url from localhost -> server ip in webUI/app/app.module.js. Ideally, there should be an option to configure the url for different environments (i.e. development, staging and production).

The score that is displayed next to a question, should be the one that is sent as the score key in Questions API. I noticed it's different from that.

Question description(text right now), should be able to parse markdown and display it in the Preview tab. This should be appropriately encoded/decoded while communicating with the backend.

Problem occurs when on "Question Update UI", and update the tags.
When try to add/remove single tag in one updation, it work perfectly.

But if I remove existing tag and add new tag in one updation, I got successful response, but then Dgraph server stops with error (While hitting api for getting tags and question):

2016/10/07 09:42:02 lists.go:169: Dirty map size: 3
2016/10/07 09:42:02 list.go:701: Idx: 0. Unable to parse posting.

This was the delete mutation for removing existing relationship of tag with question, where 0x950d84987a78b56c is question's uid:

mutation { 
  delete { 
     <_uid_:0x950d84987a78b56c> <question.tag> <_uid_:0x52408512122d7951> .
     <_uid_:0x52408512122d7951> <tag.question> <_uid_:0x950d84987a78b56c> .
   }
}

This was the final mutation, associating new tag in last line

mutation {
      set {
          <_uid_:0x950d84987a78b56c> <text> "This%20is%20the%20formatter%20question%0A%0Avar%20i%20%3D%200%3B" .
          <_uid_:0x950d84987a78b56c> <positive> "1" .
          <_uid_:0x950d84987a78b56c> <negative> "-0.6" .
           <_uid_:0x7e4f97a6b71ecbec> <name> "adad" .
          <_uid_:0x950d84987a78b56c> <question.option> <_uid_:0x7e4f97a6b71ecbec> .
          <_uid_:0xc70bd4baf809b546> <name> "fsf" .
          <_uid_:0x950d84987a78b56c> <question.option> <_uid_:0xc70bd4baf809b546> .
          <_uid_:0xc729345cc6c937d5> <name> "fsf" .
          <_uid_:0x950d84987a78b56c> <question.option> <_uid_:0xc729345cc6c937d5> .
          <_uid_:0xdae6aa3f1df3d4db> <name> "fs" .
          <_uid_:0x950d84987a78b56c> <question.option> <_uid_:0xdae6aa3f1df3d4db> .
          <_uid_:0x950d84987a78b56c> <question.correct> <_uid_:0xdae6aa3f1df3d4db> .
          <_uid_:0x950d84987a78b56c> <question.tag> <_uid_:0xc0e1495c836bc87e> .
         <_uid_:0xc0e1495c836bc87e> <tag.question> <_uid_:0x950d84987a78b56c> .
     }
}

Need to debug this.

Steps to reproduce from UI:

1. Add question with one tag associated to it.
2. Go to edit question page, remove the associated tag, add new tag.
3. Click on update button. You will get response "Successfully updated".
4. Try to access "Show all Question", Dgraph will stop/ or will give error.

View candidates page should have the option to view the candidate report for candidates who have taken the test.

Hamburger button for Menu (Gru Admin) shouldn't be visible to a candidate taking the quiz.

Score right now is mixed with positive and negative. It should be at top right.

Also, the total time left and time spent on current question should be next to it.

Right now the quiz has a box for scoring and shows the positive and the negative score within that. Ideally,we should have two boxes one below the another. The correct answer box could have green colored text and the wrong answer box text could be colored red.
This would make it easier for the candidate to see the different scores and would make this more visually appealing.

Return appropriate error to the frontend with the status code instead of log.Fatal in case you can't Decode/Encode JSON and in other cases.
