How to run single .spec file in angular5 - node.js

Hi i am writing unit test for my application using jasmine and karma.
I want to run individual test file for testing not as a whole project using npm test.
I don't want to us fdescribe()and fit().
Is there any way i can run my test file by providing filename while running test for the same.

How would I setup bamboo unit testing that runs both karma and jest

I have been trying to set up server-side testing for my application but have run into an issue with bamboo recognizing more than one test type. In the past, it worked just fine using only karma as the unit test, but I need to add server-side testing which works much better with jest.
The main problem I am running into is that when both are run as shown below the coverage report is only created for the karma(unit) tests.
test-unit=npm run test:unit && npm run test:server
I have also tried running jest under bamboos test-e2e and test-contract-test but when I do this nothing is reported. So is there a way to set up server-side testing separately in the .bamboorc file
So, I found an answer!
In the .bamboorc file move the test-unit = npm run test:unit to the end of the file and for the first test use
test-contract-consumer=npm run test:server -- --collect-coverage
This should then collect the coverage for the server tests in bamboo under the contract tests consumer artifacts, and the karma unit test should still show up under the unit test coverage artifacts.

How to prevent testing-libarary running coverage on untested files every time I save my test file?

I am using the test-library for React , and everytime I edit my test file and save it, it will automatically running coverage on other untested files and gave me a report. there are hundreds of files in my project,and it could really waste time. I don't want this, I just want it run test on my current selected file.
the command I have used is
npm run test /myprojrct/myFile.test.js
is there a way to resolve it ?
Adding the --watch flag to your test script should make jest run tests only on changed files after each save.
More details and other available options can be found here: https://jestjs.io/docs/en/cli#--watch
You should add --coverage=false flag to prevent collecting coverage.
npm run test --coverage=false
Other useful flags:
npm run test --watch // watcher will re-run only the tests that depend on the changed files
npm run test --watchAll // watcher will re-run *ALL* tests when a file has changed
npm run test -t="rendering Button" // will run only tests with a name that matches the regex
npm run test fileName.js // this argument will be treated as a regular expression to match against files in your project

Python: Unit Tests/ Integration Tests: Workaround for file paths?

I have some unit tests and integration tests I need to run in a project. The problem I face is that sometimes files are read (as mock data) and dependent on where I start the test, the relative paths has to be changed.
Is there a solution to not changing the paths, even if tests are started from different directories? (like in pycharm sometimes from a directory called 'tests' or at other times from the directory 'unit')?
For example:
I run my tests within Pycharm from a "test" directory. In one of my unit tests I read a file with the path: "../data"
Sometimes I run my tests from a directory called "unit tests" which resides in the "test" directory. Now I would have to adapt my file path from above, otherwise my file would not be found.
There are several options to solve the problem you describe:
Write a wrapper script that first sets the working directory to a fixed path before running the tests.
You could pass the absolute path in an environment variable to your test executable.
Rather than reading test data from a file, incorporate the test data into your test code.

How to run npm tests from a single folder?

Currently I am testing a React node application, and have all my tests in the root/tests folder, with components in separate folders pertaining to their function.
I have 10+ folders and 100+ tests, and would like to 'watch' a single folder while I write a test for a new component.
Currently, I am using
npm run test:watch
Which is working brilliantly, however, not only is there a lot of overhead re-running the 100 other tests not related to my new component, it's also hard to weed through all the feedback to see the results of my current test.
Is there a nice command to only watch the directory of my new test, or even the test file?
You can pass mocha test directory to the npm command:
npm run test:watch -- root/tests/subfolder
However it might depend on how your test script test:watch is defined.

Use jasmine-node to test meteor application with auto-test

I'm using jasmine-node to test my Meteor application and I want to use the auto-test feature so I don't have to rerun the tests all the time by myself.
My meteor application folder structure is like this:
server
foo.coffee
tests
foo.spec.coffee
And with the spec file I want to test code which is located in foo.coffee. I start jasmine-node with this args:
jasmine-node ./ --autotest --coffee --test-dir tests
And now I would assume that the autotest feature will react on all changes in the root folder but it just reacts on changes in the test folder. And I can't start it in the root folder because I get an error in the .meteor files (and I don't want to have jasmine testing/including the meteor code anyway).
So I want to have jasmine rerun the tests even if I change code in the server folder. How can I achieve that?
Use the --watch parameter along with --autotest and specify the directories that contain whatever files you want to have watched.
