Running pytest with coverage in a larger project, the output is strangely cut (note the datam at the end, many files are still missed here).
I'm not aware of further configuration—no pytest.ini, no pyproject.toml, no related environment variable.
How can I overcome this, given I want the simple terminal output, not an extra report?
Only if needed: How could I print the results written to .coverage sqlite database to terminal?

This looks like a bug of the coverage package, maybe from too many files (>400 in my case), maybe interference with pytest-xdist.
In such a case ignore the pytest output and print the results written to the .coverage sqlite database to terminal, like
> pytest tests --cov -n 12
...

So I am trying to run a powershell script that is triggered by TeamCity to run specific unit tests based on the names of the files that were changed on each github commit.
Here is how I am running it from the command line:
C:\MyFolder\bin\NUnit.ConsoleRunner.3.4.1\tools\nunit3-console.exe "C:\MyFolder\Bin\UnitTesting.dll" --test="MyFolder.QuickTests.DaoTests.ProductDaoTests.ProductBasicTest"
But I keep getting this, it runs it just never runs any tests:

Now when I run it without the --test command like this:
C:\MyFolder\bin\NUnit.ConsoleRunner.3.4.1\tools\nunit3-console.exe "C:\MyFolder\Bin\UnitTesting.dll"
It runs every unit-test that we have, but I don't want to run them all, I want to run specific quick ones, and only run the large ones when we go to staging/production servers so our developers don't have to wait 15 to 20 minutes every time they commit something.
Some additional info:
-My namespace that I am using for this is
MyFolder.QuickTests.DaoTests.ProductDaoTests
The Class I am calling is:
ProductBasicTest
Some of the names like the folder directories were changed because they are %teamcity% placeholders for file directories.
What am I doing wrong to not be able to run specific tests?
For some reason my nunit-console is not recognizing the /run command or /fixture or --test=.
EDIT:
I upgraded to 3.5.0 and am still getting the same issues, I am not able to use --test.
C:\MyFolder\bin\NUnit.ConsoleRunner.3.5.0\tools\nunit3-console.exe "C:\MyFolder\Bin\UnitTesting.dll" --test="MyFolder.QuickTests.DaoTests.ProductDaoTests.ProductBasicTest"
That is the new location, and getting the same issue.
When I do --where for MyFolder it crashes Powershell but doesn't actually run anything.
When I do --explore it does the same as --where for MyFolder and does nothing for MyFolder.QuickTests .
EDIT EDIT:
Thanks to Rob I found the docs here and looked at the --where function with --where "name=ProductBasicTest" which will run all the files in that Test-Suite!
So thanks to Rob one of the issues that I was running into, is it was not recognizing my namespace correctly with QuickTests. So whenever I ran the function it was not running correctly.
To fix this you can go to the Test xml file output and see what names it was running tests under.
To run these individually you can run it by the name with the command:
"nunit3-console.exe C:\PathToDll.dll --where "name = NameOfTest"
In a GitHub repository you can see “language statistics”, which displays the percentage of the project that’s written in a language. It doesn’t, however, display how many lines of code the project consists of. Often, I want to quickly get an impression of the scale and complexity of a project, and the count of lines of code can give a good first impression. 500 lines of code implies a relatively simple project, 100,000 lines of code implies a very large/complicated project.
So, is it possible to get the lines of code written in the various languages from a GitHub repository, preferably without cloning it?
The question “Count number of lines in a git repository” asks how to count the lines of code in a local Git repository, but:
You have to clone the project, which could be massive. Cloning a project like Wine, for example, takes ages.
You would count lines in files that wouldn’t necessarily be code, like i13n files.
If you count just (for example) Ruby files, you’d potentially miss massive amount of code in other languages, like JavaScript. You’d have to know beforehand which languages the project uses. You’d also have to repeat the count for every language the project uses.
All in all, this is potentially far too time-intensive for “quickly checking the scale of a project”.
You can run something like
git ls-files | xargs wc -l
Which will give you the total count →
You can also add more instructions. Like just looking at the JavaScript files.
git ls-files | grep '\.js' | xargs wc -l
Or use this handy little tool → https://line-count.herokuapp.com/
A shell script, cloc-git
You can use this shell script to count the number of lines in a remote Git repository with one command:
#!/usr/bin/env bash
git clone --depth 1 "$1" temp-linecount-repo &&
printf "('temp-linecount-repo' will be deleted automatically)\n\n\n" &&
cloc temp-linecount-repo &&
rm -rf temp-linecount-repo
Installation
This script requires CLOC (“Count Lines of Code”) to be installed. cloc can probably be installed with your package manager – for example, brew install cloc with Homebrew. There is also a docker image published under mribeiro/cloc.
You can install the script by saving its code to a file cloc-git, running chmod +x cloc-git, and then moving the file to a folder in your $PATH such as /usr/local/bin.
Usage
The script takes one argument, which is any URL that git clone will accept. Examples are https://github.com/evalEmpire/perl5i.git (HTTPS) or git#github.com:evalEmpire/perl5i.git (SSH). You can get this URL from any GitHub project page by clicking “Clone or download”.
Example output:
$ cloc-git https://github.com/evalEmpire/perl5i.git

Alternatives
Run the commands manually
If you don’t want to bother saving and installing the shell script, you can run the commands manually. An example:
$ git clone --depth 1 https://github.com/evalEmpire/perl5i.git
$ cloc perl5i
$ rm -rf perl5i
Linguist
If you want the results to match GitHub’s language percentages exactly, you can try installing Linguist instead of CLOC. According to its README, you need to gem install linguist and then run linguist. I couldn’t get it to work (issue #2223).
I created an extension for Google Chrome browser - GLOC which works for public and private repos.
Counts the number of lines of code of a project from:
project detail page
user's repositories
organization page
search results page
trending page
explore page
If you go to the graphs/contributors page, you can see a list of all the contributors to the repo and how many lines they've added and removed.
Unless I'm missing something, subtracting the aggregate number of lines deleted from the aggregate number of lines added among all contributors should yield the total number of lines of code in the repo. (EDIT: it turns out I was missing something after all. Take a look at orbitbot's comment for details.)
UPDATE:
This data is also available in GitHub's API. So I wrote a quick script to fetch the data and do the calculation:
'use strict';
async function countGithub(repo) {
const response = await fetch(`https://api.github.com/repos/${repo}/stats/contributors`)
const contributors = await response.json();
const lineCounts = contributors.map(contributor => (
contributor.weeks.reduce((lineCount, week) => lineCount + week.a - week.d, 0)
));
const lines = lineCounts.reduce((lineTotal, lineCount) => lineTotal + lineCount);
window.alert(lines);
}
countGithub('jquery/jquery'); // or count anything you like
Just paste it in a Chrome DevTools snippet, change the repo and click run.
Disclaimer (thanks to lovasoa):
Take the results of this method with a grain of salt, because for some repos (sorich87/bootstrap-tour) it results in negative values, which might indicate there's something wrong with the data returned from GitHub's API.
UPDATE:
Looks like this method to calculate total line numbers isn't entirely reliable. Take a look at orbitbot's comment for details.
You can clone just the latest commit using git clone --depth 1 <url> and then perform your own analysis using Linguist, the same software Github uses. That's the only way I know you're going to get lines of code.
Another option is to use the API to list the languages the project uses. It doesn't give them in lines but in bytes. For example...
$ curl https://api.github.com/repos/evalEmpire/perl5i/languages
{
"Perl": 274835
}
Though take that with a grain of salt, that project includes YAML and JSON which the web site acknowledges but the API does not.
Finally, you can use code search to ask which files match a given language. This example asks which files in perl5i are Perl. https://api.github.com/search/code?q=language:perl+repo:evalEmpire/perl5i. It will not give you lines, and you have to ask for the file size separately using the returned url for each file.
Not currently possible on Github.com or their API-s
I have talked to customer support and confirmed that this can not be done on github.com. They have passed the suggestion along to the Github team though, so hopefully it will be possible in the future. If so, I'll be sure to edit this answer.
Meanwhile, Rory O'Kane's answer is a brilliant alternative based on cloc and a shallow repo clone.
From the #Tgr's comment, there is an online tool :
https://codetabs.com/count-loc/count-loc-online.html
You can use tokei:
cargo install tokei
git clone --depth 1 https://github.com/XAMPPRocky/tokei

Tokei has support for badges:
Count Lines
[](https://github.com/XAMPPRocky/tokei)
By default the badge will show the repo's LoC(Lines of Code), you can also specify for it to show a different category, by using the ?category= query string. It can be either code, blanks, files, lines, comments.
Count Files
[](https://github.com/XAMPPRocky/tokei)
You can use GitHub API to get the sloc like the following function
function getSloc(repo, tries) {
//repo is the repo's path
if (!repo) {
return Promise.reject(new Error("No repo provided"));
}
//GitHub's API may return an empty object the first time it is accessed
//We can try several times then stop
if (tries === 0) {
return Promise.reject(new Error("Too many tries"));
}
let url = "https://api.github.com/repos" + repo + "/stats/code_frequency";
return fetch(url)
.then(x => x.json())
.then(x => x.reduce((total, changes) => total + changes[1] + changes[2], 0))
.catch(err => getSloc(repo, tries - 1));
}
Personally I made an chrome extension which shows the number of SLOC on both github project list and project detail page. You can also set your personal access token to access private repositories and bypass the api rate limit.
You can download from here https://chrome.google.com/webstore/detail/github-sloc/fkjjjamhihnjmihibcmdnianbcbccpnn

Hey all this is ridiculously easy...
Create a new branch from your first commit
When you want to find out your stats, create a new PR from main
The PR will show you the number of changed lines - as you're doing a PR from the first commit all your code will be counted as new lines
And the added benefit is that if you don't approve the PR and just leave it in place, the stats (No of commits, files changed and total lines of code) will simply keep up-to-date as you merge changes into main. :) Enjoy.
Firefox add-on Github SLOC
I wrote a small firefox addon that prints the number of lines of code on github project pages: Github SLOC
npm install sloc -g
git clone --depth 1 https://github.com/vuejs/vue/
sloc ".\vue\src" --format cli-table
rm -rf ".\vue\"
Instructions and Explanation
Install sloc from npm, a command line tool (Node.js needs to be installed).
npm install sloc -g
Clone shallow repository (faster download than full clone).
git clone --depth 1 https://github.com/facebook/react/
Run sloc and specifiy the path that should be analyzed.
sloc ".\react\src" --format cli-table
sloc supports formatting the output as a cli-table, as json or csv. Regular expressions can be used to exclude files and folders (Further information on npm).
Delete repository folder (optional)
Powershell: rm -r -force ".\react\" or on Mac/Unix: rm -rf ".\react\"
Screenshots of the executed steps (cli-table):
sloc output (no arguments):
It is also possible to get details for every file with the --details option:
sloc ".\react\src" --format cli-table --details
Open terminal and run the following:
curl -L "https://api.codetabs.com/v1/loc?github=username/reponame"
If the question is "can you quickly get NUMBER OF LINES of a github repo", the answer is no as stated by the other answers.
However, if the question is "can you quickly check the SCALE of a project", I usually gauge a project by looking at its size. Of course the size will include deltas from all active commits, but it is a good metric as the order of magnitude is quite close.
E.g.
How big is the "docker" project?
In your browser, enter api.github.com/repos/ORG_NAME/PROJECT_NAME
i.e. api.github.com/repos/docker/docker
In the response hash, you can find the size attribute:
{
...
size: 161432,
...
}
This should give you an idea of the relative scale of the project. The number seems to be in KB, but when I checked it on my computer it's actually smaller, even though the order of magnitude is consistent. (161432KB = 161MB, du -s -h docker = 65MB)
Pipe the output from the number of lines in each file to sort to organize files by line count.
git ls-files | xargs wc -l |sort -n
This is so easy if you are using Vscode and you clone the project first. Just install the Lines of Code (LOC) Vscode extension and then run LineCount: Count Workspace Files from the Command Pallete.
The extension shows summary statistics by file type and it also outputs result files with detailed information by each folder.
There in another online tool that counts lines of code for public and private repos without having to clone/download them - https://klock.herokuapp.com/
None of the answers here satisfied my requirements. I only wanted to use existing utilities. The following script will use basic utilities:
Git
GNU or BSD awk
GNU or BSD sed
Bash
Get total lines added to a repository (subtracts lines deleted from lines added).
#!/bin/bash
git diff --shortstat 4b825dc642cb6eb9a060e54bf8d69288fbee4904 HEAD | \
sed 's/[^0-9,]*//g' | \
awk -F, '!($2 > 0) {$2="0"};!($3 > 0) {$3="0"}; {print $2-$3}'
Get lines of code filtered by specified file types of known source code (e.g. *.py files or add more extensions, etc).
#!/bin/bash
git diff --shortstat 4b825dc642cb6eb9a060e54bf8d69288fbee4904 HEAD -- *.{py,java,js} | \
sed 's/[^0-9,]*//g' | \
awk -F, '!($2 > 0) {$2="0"};!($3 > 0) {$3="0"}; {print $2-$3}'
4b825dc642cb6eb9a060e54bf8d69288fbee4904 is the id of the "empty tree" in Git and it's always available in every repository.

How to get Git diff of the first commit?
Is there a way of having git show lines added, lines changed and lines removed?
shields.io has a badge that can count up all the lines for you here. Here is an example of what it looks like counting the Raycast extensions repo:
You can use sourcegraph, an open source search engine for code. It can connect to your GitHub account, index the content, and then on the admin section you would see the number of lines of code indexed.
I made an NPM package specifically for this usage, which allows you to call a CLI tool and providing the directory path and the folders/files to ignore
it goes like this:
npm i -g #quasimodo147/countlines
to get the $ countlines command in your terminal
then you can do
countlines . node_modules build dist
I am running Rails 2.3.5.
In my project I have in lib/tasks the following rake task (test_task.rake):
desc 'test_synchro_task'
task :test_synchro_task => :environment do
# A bunch of things that are properly executed (basically I am inserting
# in the database)...
# ...
# and once the above is done, I want the following to be executed,
# the sphinx index to be rebuild, but it is NOT :
system("cd /sites/project/app")
system("RAILS_ENV='staging' rake ts:index")
end
I trigger the execution of the task via a crontab containing the following entry:
13 14 * * * cd /sites/project/app && /sites/ruby/bin/rake RAILS_ENV=staging test_task
which id correctly called and executed except for 2 system lines in the task.
Please note that when I place those 2 system lines in a ruby test.rb file in my project script directory, and run it manually using the ruby command:
ruby test.rb
those 2 system commands are properly executed and the index is rebuilt correctly.
In my rake task I tried replacing those 2 system lines by:
%x["cd /sites/project/app"]
%x["RAILS_ENV='staging' rake ts:index"]
or by
#cmd="cd /sites/project/app; RAILS_ENV='staging' rake ts:index"
`#{#cmd}`
but the rake ts:index is still not executed.
Any idea why?
Many thanks.
Yves
Problem resolved:
1- In the ruby script, I found that the $?.exitstatus was 127, which is "command not found".
2- This hinted me to a PATH problem occurring in the context of cron.
3- Found that post: http://dewful.com/?p=157 titled "Ruby - Cron Not Working For Ruby Script".
4- Added the PATH in the crontab and everything works fine.
