The IDE says that it can't run tests Introduction / Getting started / Hello World

[edutools-service]

The IDE cant run test, you cannot complete the question on Idea Commnunity, (I test this in 2 diferent linux distributions) and not found any solution on internet
No tests have run. For more information, see the Troubleshooting guide

It is happening to me, if you look in the directory the test should be blank:

❯ cd ~/Downloads/rust/Learn Rust/Introduction/Getting started/Hello World

❯ ls -lha tests/tests.rs
.rw-r--r-- wolf users 0 B Sun Jun 11 09:59:09 2023  tests/tests.rs

❯ ls -lha src/main.rs
.rw-r--r-- wolf users 45 B Sat Jun 10 02:56:15 2023  src/main.rs

But in this repository, the test file has some code. I wonder why it is empty. Let me try to do some tests to check if I find a solution.

You can get the path with these steps:

I found the possible problem, but it needs confirmation from JetBrains Academy.

If you go to the plugin page, Learn Rust in the version section. Then download the file version 17. And extract the Zip file, it will show a JSON file (course.json) with the structure and information of the course. Analyzing it, for example in the “Hello World” section it is missing the test file, for that reason, it should be created in the folder test with an empty file test.rs, every time you run the check button in your course.

But, in this repository exists the test file with the code Introduction/Getting started/Hello World/tests/tests.rs.

Possible solution: I will download this repository, then copy and paste all the folders (Introduction, Common Collections, etcetera) into my directory created by JetBrains academy, in my case is ~/Downloads/rust/Learn Rust. Or maybe, my first test is to copy all the content in the repository folder into ~/Downloads/rust/Learn Rust.

I copied all the files and content from this repository to the created folder by JetBrains Academy, and it didn't work.

I copy only the test*.rs files and it is much better. For this command, I had both folders under the same directory: ./Learn Rust (it is the created folder for JetBrains Academy) and ./rustlings-course which is this repository.

cd ./rustlings-course
find . -type f -iname "*test*\.rs" -exec cp -r --parents {} ../Learn\ Rust \;
cd ..

---

Next problem: every time I click the check button, it runs this command:

/home/wolf/.cargo/bin/cargo test --message-format=json-diagnostic-rendered-ansi --no-run --color never --manifest-path "/home/wolf/Downloads/rust/Learn Rust/Introduction/Getting started/Hello World/Cargo.toml"

It will never run the test because this command has a parameter for “not run”.

Furthermore, every time the check button is tapped, the test files copied from this repository are returned to empty files.

---

On the other hand, if you try to run in the Cargo in the CLion as the tutorial of this manual shows in the Introduction section, then it is working, but it doesn't make the check in the course.

Not forget to copy the test files from this repository:

cd ./rustlings-course
find . -type f -iname "*test*\.rs" -exec cp -r --parents {} ../Learn\ Rust \;
cd ..

/home/wolf/.cargo/bin/cargo test --color=always --test tests --manifest-path "/home/wolf/Downloads/rust/Learn Rust/Introduction/Getting started/Hello World/Cargo.toml"

The output is:

Final note:

I don't know exactly what is the problem or problems, but I hope that this little research helps to fix this course. I am very exciting about completing it, but if every time I tap the check button it didn't work, at some time is a little frustrating.

same question on IDEA 2023.2 and 2023.1.5

[sofiiako]

@DaniilBogdanovJB could you please take a look at this? all the earlier unassigned issues seem to be somehow related

[DaniilBogdanovJB]

Hello there,
I had no luck reproducing this problem on the latest IDEA and CLion (both community and Ultimate) on Win, Linux, and MacOS.

Please try removing the course project folder, re-downloading it from the Academy Marketplace, and checking if the problem is still reproducible.

[airvzxf]

It is true, it is working. Maybe some fix from this repository or the rustlings-course, or some fix from JetBrains IDEs.

I tested this morning (9 hours ago) and it is working. In a few days or weeks, I'll format my computer and re-install Arch Linux, I'll test again and provide comments on this issue.

Attached the evidence.

[Xmarmalade]

After I updated IDEA and recreated the project, the tests are still not available.

IntelliJ IDEA 2023.2.1 (Ultimate Edition)
Build #IU-232.9559.62, built on August 23, 2023

I tried 'Repair IDE' , but this doesn't seem to work

[Xmarmalade]

After deleting all data related to JetBrains IDE: %APPDATA%/JetBrains and %LOCALAPPDATA%/JetBrains, my test function finally works

[DaniilBogdanovJB]

We found some an interesting detail regarding this issue:
If you disable "Show test results in the Test tool window" in Settings | Advanced Settings | Rust the error becomes reproducible with every test. IDE suggests toggling off this setting sometimes.
Removing the config directory (hard reset) or enabling it again restores functionality, so if anyone meets this problem - first try checking this setting.
