artemis's Issues

✅ Extend Protractor End-to-End Tests for Quiz Exercises

Is your request related to a problem?

We want to prevent regression errors in ArTEMiS.

Describe the solution you'd like

We should add e2e tests for

creation, and
participation

of Quiz Exercises.

Additional context

We introduced Protractor End-to-End Tests in #140.
Right now, they cover Course creation and deletion, as well as login.

Support team work

There are several issues that we need to address:

Access Management: Configure in Artemis which groups should be used from the user management service
Repository creation: As soon as one student starts the exercise, repository and build plan will be created. For other students of the same team / group, the exercise is already startet on the web interface of Artemis
Special case online editor: as soon as a student from a group opens the online exercise the first time, a new version of the same remote team repository is cloned to the Artemis server for this student --> important: then merge conflicts need to be handled properly and the student needs the possibility to choose which version should be used

Special case: If real-time collaboration should be supported: use websockets and only create one repository

Special case LTI: All students need to initialize the LTI connection. Artemis needs to report the score to all students of that group over LTI.

Required changes in the object model / database:

Add a group object and connect it to a participation with that group --> use JHipster mechanism liquibase

Challenge: How can we identify how much a student contributed to the test success: for example each commit creates a new build: identify how many test cases are green after this build that have been red before.

Save attribute / method after dismissing with click outside

Is your feature request related to a problem?

E.g. when I add an attribute to a class, I click outside the popover and expect the application to save. Currently the application just drops my input.

Describe the solution you'd like

Clicking outside the popover should add the property.

Describe alternatives you've considered

Add a button next to the input so I can click on it to save.

Show max points for exercises in the course dashboard

If max points is specified for an exercise, it should be shown in the course dashboard next to the exercise

Downloading PDF file gives you f.txt file 🐛

Describe the bug

Instead of a PDF file you will be offered by Google Chrome a txt file with the name "f"

To Reproduce

Steps to reproduce the behavior:

Go to Artemis POM Lectures
Click on Lecture 1 Attachment with the slides
Try to save file to disk
See error

Expected behavior

A PDF file with the correct name and the .pdf file extension

Environment

 - OS: [Win10 Home]
 - Browser [chrome]
 - Version [73]

Change "Creation" Message after starting a UML exercise

Text exercise: Visual indication for feedback; colours are not optimal

Is your feature request related to a problem?

A red or yellow colour might confuse the student as it looks "wrong", but the colour is just used to indicate the relationship between the assessment and the student's answer.

Describe the solution you'd like

Display the feedback when clicking on the answer (similar to the "notes" of Moodle that are attached to the PDF / image).

Describe alternatives you've considered

Use lines that show up on hovering and connects the answer with the tutor's feedback.

Group and Sort Exercises in Course Dashboard

Allow users to group the exercises according to:

Exercise Type
Release Date
Due Date (standard)

For Release Date and Due Date, it should be displayed on a weekly basis

Clone Repository: Hide & copy password

As a student, it should be possible to hide the sown password and copy it to the clipboard.

Setup Programming Exercise directly on ArTEMiS

Create a Project in VCS with 3 repos: exercise, test, solution
Create a Project in CI with 2 build plans: BASE, SOLUTION
Configure access rights for both systems
Create example test cases and the correct pom.xml file in the test repo
Create an Eclipse project, gitignore, README example, one Main.java file in the correct package path (including src) in the template repo
Create an Eclipse project, gitignore, README example, one Main.java file in the correct package path (including src) in the solution repo

The following variables are shown in the user interface when the instructor creates the exercise:

Exercise Name/Title
Exercise ShortName
Course ShortName (should be added to Course)
Programming Language (default Java)
Package Path (for Java, e.g. "de.tum.in.www1")
optional: Main Class name
optional boolean: includeStructuralTestFramwork (it always includes one example of a behavior test)

All required files are stored within ArTEMiS' src --> config folder so that this feature can be deployed self-contained

Allow TAs to download certain repos as zip files in the instructor exercise dashboard

Add a new button with a popup. In the popup, TAs can enter student identifiers in a comma separated list. When they click on Download, a new GET REST call on the server (comparable to ExerciseResource and ExerciseService --> Archive) checks if the students with these identifiers have participated in the exercise, clones all repos, zips them in a file and returns this as input stream so that the file can be downloaded in the angular client.

Export / import questions

To make it easier to reuse quiz questions in future quizzes, an export / import mechanism into a structured file format would be useful

🐛 Text exercise: Stuck on finding new assessment

Stuck on finding new assessment

Environment

Chrome

Support reset of online code editor in case of merge conflicts

Currently, Artemis detects merge conflicts and shows an error message to the student, but cannot handle them properly, e.g. in case the online editor version contains changes that conflict with new commits in the remote repository.

One solution would be that the student gets the chance to reset the online editor version to the remote repository (or even better, but more complex: the student can choose which version should be kept, either the online editor version or the remote version)

Entry point to this issue would be https://github.com/ls1intum/ArTEMiS/blob/master/src/main/java/de/tum/in/www1/exerciseapp/service/GitService.java --> Method pull --> insert a try catch to handle this case properly

Show score in %

As a student, my current score should be clearly visible within the Online Editor.

Access old courses🚀

During my structured evaluation interviews for the tutors related dashboards, I collected a feedback from a tutor who asked to be able to access old courses, as a student, also after a courses is ended. They say material shared during the course is useful, and would be cool to be able to go back and review what have been done after a course is ended

Add Analytics

To track the usage of ArTEMiS it would be great to add Analytics/Tracking tools

Allow download of build artifacts

While conducting an exercise about Build and Release Management, students should be able to download the build artifact (e.g. JAR).

Participation Site unresponsive

If there are many participations, the corresponding site gets unresponsive, because all participations are loaded. Is there a quick fix that solves the problem? I could imagine the following solutions:

Paging: Only load a predefined number of participations (e.g. 20, 50, 100, maybe even configurable)
Immediately filter: before loading the results, the user has to filter the exercise
Data loading happens in the background and the site stays responsive

With respect to performance, I would prefer options 1 or 2.

Set email address of commits by ArTEMiS

Otherwise it defaults to the name of the current linux user, which is currently "montag".

Purge build plans on CI server

After the due date of an exercise, it would be good, if Artemis can delete all student build plans on the CI server without deleting data in the Artemis database so that statistics and results are still available. Another possibility would be to manually start this purge mechanism.

The repositories in the VCS don't need to be deleted, so that student could theoretically resume their exercise (in this case only the build plan would be recreated).

To allow for better statistics, Artemis should store the following CI date in its database:

Results of each test case (this would require a change of the object model / database)
maybe: build log (but this should not be interesting)

important: in case of build output files (e.g. jars in release management exercises), the build outputs would be lost, but in this case students could resume the exercise and create the build output again

Instructions panel can't be scrolled to the bottom

Describe the bug

The instructions panel of an exercise can't be scrolled until the bottom. Some parts of the class diagram can't be seen.

Environment

 - OS: macOS Mojave 10.14.3
 - Browser: Chrome 73.0.3683.86
 - Version: Artemis 3.0.0

ArrayIndexOutBoundsException when invalid Bitbucket URL is given.

When an invalid URL (with less then 3 slashes in the path), is given when creating a programming exercise, an ArrayIndexOutBoundsException occurs.

Add continuous code quality monitoring

Hey, great to see how development continues on this project!

I recently stumbled upon Codacy, a tool for analyzing and monitoring code quality. Besides highlighting code quality issues, it also gives explanations why certain things are an issue, so it is also a great chance for all contributors to improve their skills.

How about trying it out on ArTEMiS? It's free for open source projects.

Cheers,
Dominik

Add existing question

To reuse existing questions (from other courses), we need a popup with a search and filter mechanism to select an existing quiz questions.

Label exercises with categories

For the calculation of bonus scores with different kind of exercises, it would be helpful to allow instructors to tag exercises with keywords.
These keywords are then used to filter for certain exercises when calculating the score of students

🚀 undo

Is your feature request related to a problem?

I'm frustrated taht I cannot undo/redo my changes in the Modeling Editor

Describe the solution you'd like

An undo/redo function

Present Sample Solution

As Instructor, I want to be able to provide a sample solution for an exercise.
As Student, I want to see a sample solution of an exercise after the exercise deadline has passed.

Collapse or hide courses

The following feature has been suggested by a student:

it would be very neat to make it possible to collapse courses in the „courses overview“. For instance, in my screen, EIST and other „old“ lectures are shown but not relevant to me now. Maybe a filter option what should be displayed would be even better.

Leave or hide courses

Is your feature request related to a problem?

There is no way of leaving a course.

Describe the solution you'd like

I would like to be able to leave a course as a student.

Participation Details broken

Steps to reproduce:

Select an Exercise
Select the Participations

Expected: Timestamps etc. are shown
Actual: Only template placeholders are shown

Export Quiz Statistics

To analyze the quiz participation, it would be nice to have an option to download which student selected which answer option in the quiz, e.g. using the following json structure

{
"Questions": [
{
"Question": "This is a Question",
"Answers": [
{
"Text": "This is answer a",
"Correct": true
},
{
"Text": "This is answer b",
"Correct": true
}
]
},
{
"Question": "This is another Question",
"Answers": [
{
"Text": "This is answer a",
"Correct": false
},
{
"Text": "This is answer b",
"Correct": true
}
]
}
],
"Students": [
{
"LRZ": "ab12cde",
"CourseOfStudy": "ComputerScience",
"Answers": [
{
"SelectedItems": [
1,
2
]
},
{
"SelectedItems": [
1
]
}
]
},
{
"LRZ": "cd12efg",
"CourseOfStudy": "TUMBWL",
"Answers": [
{
"SelectedItems": [
6,
2,
3
]
},
{
"SelectedItems": []
}
]
},
{
"LRZ": "de34ged",
"CourseOfStudy": "TUMBWL",
"Answers": []
}
]
}

Support new statistics

Create bar charts how many students solved the exercise correctly and how many failed for a specific exercise

Create bar charts for the whole course

Specify the difficulty level of exercises

Instructors should be able to specify the difficulty level "easy", "medium" and "hard" for exercises. This should then be shown to students in the course dashboard next to the exercise

Can't delete course

A course cannot be deleted because of sql constraint violations.
If a course is deleted ArTEMiS (hibernate to be more precise) tries to set the foreign key exercise.course to null, but null values are forbidden.

Supporting deleting courses may require a on delete cascade sql constraint rule (and not on delete set null). However, that means that not only the course is deleted, but also all exercises, participations and results (git repo's and bamboo build plans might have to be deleted manually; on delete cascade only clears the database)

Emtpy TextInput after Deletion of attribute/method

Use a better date time picker for exercise management

The built in date time picker does not work on all browsers and has a very limited usability, we should switch to something like https://github.com/DanielYKPan/date-time-picker

Properties popover auto closes when auto-save triggers

It seems that the auto-save closes the properties popover (when editing a class or association).

Environment

 - OS: macOS Mojave 10.14.3
 - Browser: Chrome 73.0.3683.86
 - Version: Artemis 2.8.0

Make Quiz Exercises Test run for TAs more visible when exercise is not released

Currently, tutors can see quiz exercises, but they cannot test them if they are not yet released. To get a feeling for the quiz and to be able to (easily) check the quiz setup and content, it would be good if tutors would be able to participate in quizzes before they are released, similar to the coding exercises.

Crash & Error Reporting

To get more insights about crashes and errors, we should integrate error reporting tools.

Alert the creator of a quiz question if the (short) question title is too long.

The (short) question title seems to be limited to a certain length. However, this is not visible to the creator of a quiz question. Saving of the question will fail with a very unspecific error message.

The console shows the following:

Failed to load resource: the server responded with a status of 500 ()
Saving Quiz Failed! Please try again later.

Ideally, the question creator should be directly informed if the text field's data is longer than the allowed amount of characters before trying to save.

InternalServer Error when editing a Course

When editing a course the overlay shows an InternalServerError. Nonetheless, the system seems to work as expected. See attached Screenshot:

Show Exercises which are not assigned to a course

When you create a new exercise, and you do not assign it to a course it is no longer editable nor visible in the overview.

Overview Participations for a specific course

As instructors, we want to have the possibility to see/analyze the data for students for a specific course. For example, I want to easily check the overall participations of student A for the course B which had in total 16 exercises so far.
I want to know, in how many exercises the students participated (14 out of 16).

Create files

As a student, it should be possible to create new files within the Online Editor.

Make the "Report a bug" and "Request a Feature" buttons more prominent

Is your feature request related to a problem?

It's not visible right away if someone is having a problem.

Describe the solution you'd like

Either fixed on one of the sides or top of the editing window.

Show build log if compiling fails

Currently, if compiling fails, ArTEMiS only shows "No tests founds (Check for compile errors)". There should be a possibility to get the detailed error message from the Bamboo build log.

Support new exercise types

It would be nice if Artemis is able to support other exercises than coding, e.g. modeling or quizzes

Required changes:

Adapt the object model / database: Create sub classes for the Exercise class, e.g. programming exercise, modeling exercise, etc and customize the exercise types by that
Configure the exercise without build plan
Extend the flag "allowOnlineEditor" to use different types of online views / editors, e.g. a modeling canvas or a quiz interface
Define a storage for the exercise type
4a) Quizzes: e.g. Markdown (think about if it makes sense to store in a repository)
4b) Modeling exercise: Create a new version of the online editor and possibly reuse existing Angular components, see https://github.com/ls1intum/ArTEMiS/blob/master/src/main/webapp/app/editor/editor.html
Configure the view for instructor / teaching assistants who review the results and who insert feedback

Split courses by semester🚀

During my structured evaluation interviews for the tutors related dashboards, I collected a feedback from a tutor who said that it would be cool to have the courses split by semesters, to see in which semester some course have been taken.

I think #319 is a necessary prerequisite for this

"Clone repository" modal does not disappear
