Introduction
The Codecov Bash uploader provides a language-agnostic alternative for sending your coverage reports to Codecov. Its usage is both simple and convenient:
bash <(curl -s https://codecov.io/bash)
The main objectives of the uploader are to:
- detect the environment
- gather reports
- upload them to Codecov
The above command silently requests the latest version of the uploader from Codecov and executes via Bash; all output is directed to stdout
.
Upload token
Not Required for some CI Providers
If you have a public project on TravisCI, CircleCI, AppVeyor, Azure Pipelines, or GitHub Actions an upload token is not required.
A unique upload token is required to identify which project the coverage belongs to. This token is located in the repository settings (/<github>/<owner>/<repo>/settings
).


A repository on codecov with no uploaded coverage reports. Note the upload token.
There are three ways to provide the upload token to the Bash uploader:
Flag
bash <(curl -s https://codecov.io/bash) -t token
Environment variable
export CODECOV_TOKEN="token"
bash <(curl -s https://codecov.io/bash)
Loading token from a file
echo "token" > .cc_token
bash <(curl -s https://codecov.io/bash) -t @.cc_token
CI detection
The bash uploader detects all CI providers through environment variables. This process helps to identify the source of the build and maintain a relationship back to the source of the coverage collection.
- Using Docker? Please review Testing with Docker.
- Using Python Tox? Please review Testing with Tox.
Finding reports and specifying file names
Codecov can automatically detect coverage files in your project. A thorough filename search will grab everything that is known to be a coverage report. You can also specify exactly which file(s) should be uploaded.
Here are some options for discovering report files:
# only upload this file
-f path/to/foo.bar
# also search this folder that is outside the project directory
-s /home/user/reports/foo/bar
# ignore all files at pattern *.bar
-f "!*.bar"
# include all files at pattern *.foo
-f "*.foo"
Uploading process
When the upload script is called, the general flow is as follows:
- The CI is discovered through environment variables.
- Language specific processing and formatting (e.g. xcode, python).
- Reports are found in the filesystem.
- Reports are prepended with file paths and appended with file adjustments.
- Reports are uploaded to cloud storage for archiving (secret location).
- Codecov is informed of the upload, and will queue the report processing server side.
- Done (
exit 0
).
Exit 0
Codecov will
exit 0
to prevent failing the build, if there are issues. If you would like Codecov to exit with1
, usebash <(curl -s https://codecov.io/bash) -Z
.
exit 0
is not foolproof. Please use this command to always exit with0
:bash <(curl -s https://codecov.io/bash) || echo 'Codecov failed to upload'
.
Verbose mode
If there is an issue with the upload process, it helps to run in verbose mode. Supply the
-v
flag for better debugging output:
bash <(curl -s https://codecov.io/bash) -v
Arguments
The bash uploader provides various arguments to work with many complex environments. Listed below are the full list of possible arguments and their usage.
Argument | Usage |
---|---|
| Extra curl arguments to communicate with AWS. |
| Move discovered coverage reports to the trash |
| Don't upload, but dump upload file to stdout |
| Specify environment variables to be included with this build
|
| Flag the upload to group coverage metrics |
| Target file(s) to upload Must use single quotes. |
| Display this help and exit |
| Remove color from the output |
| The commit SHA of the parent for which you are uploading coverage. If not present, the parent will be determined using the API of your repository provider. When using the repository provider's API, the parent is determined via finding the closest ancestor to the commit. |
| Custom defined name of the upload. Visible in Codecov UI |
| Write upload file to path |
| Used when not in git/hg project to identify project root directory |
| Directory to search for coverage reports. |
| Set the private repository token
|
| Extra curl arguments to communicate with Codecov. e.g., |
| Verbose mode |
| Toggle functionalities
|
| Exit with 1 if not successful. Default will Exit with 0 |
enterprise | |
| owner/repo slug used instead of the private repo token in Enterprise |
| File path to your cacert.pem file used to verify ssl with Codecov Enterprise (optional) |
| Set the target url for Enterprise customers |
env vars | Used to override pre-existing CI environment variables |
| Specify the branch name |
| Specify the build number |
| Specify the commit sha |
| Specify the pull request number |
| Specify the git tag |
gcov | |
| Extra arguments to pass to gcov |
| Paths to include during gcov gathering |
| Paths to ignore during gcov gathering |
| Prefix filepaths to help resolve path fixing |
| Project root directory |
| gcov executable to run. Defaults to |
xcode | |
| Custom Derived Data Path for Coverage.profdata and gcov processing |
| Specify packages to build coverage. Uploader will only build these packages. |
