codecov/project status measures overall project coverage and compares it against the base of the pull request or parent commit.
coverage: status: project: default: # basic target: auto threshold: 0% base: auto flags: - unit paths: - "src"

Flags are a list of user defined Flags, and the impact on their coverage. You can specify an array of flags as follows:
coverage: status: project: default: #... flags: - flag1 - flag2 - ...
and the combined coverage from those flags will be reported. Before using flags, it is highly recommended to read more about their use.
Similar to flags, an array of paths and/or regular expressions can be provided and the status will report the combined coverage for the files that match the path name / regular expression.
While Codecov defaults should be sufficient for most use cases, below are some advanced features to personalize your experience even more.
The branches that, when used, will trigger this status.
Supports regex patterns and the exclude operator (
branches: - master if_ci_failed: error #success, error informational: false only_pulls: false
Settings are 'success' and 'failure' the default is 'success'.
failure: the status will fail if there is no report for the head
success: the status will pass if there is no report for the head. Use this on commits / PRs where you won't be uploading coverage but still want codecov status checks to pass.
Use Codecov in informational mode. Default is
true is specified the resulting status will pass no matter what the coverage is or what other settings are specified. Informational mode is great to use if you want to expose codecov information to other developers in your pull request without necessarily gating PRs on that information.
Only post a status to pull requests, defaults to
true no status will be posted for commits not on a pull request
Settings are 'success' and 'error' the default is 'error'.
error: Will set the status to success only if the CI is successful
success: Will set the status to success even if the CI fails
Determines how we handle status checks for which no flag coverage has been newly uploaded on a commit. This includes status checks where flags have carriedforward coverage (since coverage was no newly uploaded), as well as flags for which coverage is missing entirely.
include: (default) All the status checks defined in the YAML file will be processed and sent as normal.
exclude: Status checks that haven't newly uploaded any flag coverage will not be sent.
pass: Status checks that haven't newly uploaded any flag coverage will be passed automatically.
This is useful if, for example, you're working on a project in a monorepo and don't want to see status checks related to other projects.
Note that this only applies to status checks that specify flags. If there are no flags on a check, the status check will be processed as usual.
Below is an example of using the
flag_coverage_not_uploaded behavior to omit status checks from unrelated projects.
coverage: status: default_rules: flag_coverage_not_uploaded_behavior: exclude # don't send status checks that don't have flag coverage uploaded project: projectA: target: auto flags: - projectA-unit - projectA-integration projectB: target: auto flags: - projectB
In this example, if a PR is opened in
projectB then the status check for
projectA won't be sent, as long as no coverage for
projectA was uploaded on the PR.
Note that this requires that the CI process in
projectB only uploads to Codecov using the
projectB flag, and does not upload anything under the
projectA flag. If your CI runs all tests and uploads coverage for every flag specified in the YAML file on every commit, then all status checks will appear as normal.
Below, is an example of using multiple project statuses that measure different aspects of your project.
coverage: status: project: default: false # disable the default status that measures entire project tests: # declare a new status context "tests" target: 100% # we always want 100% coverage here paths: "tests/" # only include coverage in "tests/" folder app: # declare a new status context "app" paths: "!tests/" # remove all files in "tests/"
Now you will see two unique status contexts from Codecov:
You may have a code base that has multiple application components that you would like to monitor independently. Codecov provides a very simple way create statuses for each component.
coverage: status: project: users: paths: - tests/users - app/components/user* products: paths: - tests/products - app/components/product*
codecov/patch status only measures lines adjusted in the pull request or single commit, if the commit is not in a pull request. This status provides an indication on how well the pull request is tested.
coverage: status: patch: default: # basic target: auto threshold: 0% base: auto # advanced branches: - master if_ci_failed: error #success, error only_pulls: false flags: - "unit" paths: - "src"
To illustrate the usage of the patch status, let's go through this exercise.
def divide(x, y): + if y <= 0: + raise ValueError("y must be greater than 0") return x * y
codecov/patch status of this commit would be
0% covered because no tests are created for this method. Even though the project coverage is 72% (the entire code base not shown), this patch status will only measure lines added.
To make another commit on this pull request, adding tests, proceed as follows.
+ def test_divide_by_1(self): + assert divide(10, 1) == 10
Running the tests will result in a patch coverage of
50% covered because we have not yet tested the behavior of dividing by zero. Let's add another test.
def test_divide_by_1(self): assert divide(10, 1) == 10 + def test_divide_by_zero(self): + with self.assertRaises(ValueError) + divide(1, 0) +
Now Codecov will report a
codecov/patch status of
100% covered for this pull request. This indicates that the pull request adjusted code is properly executed by tests.
You may choose to disable the default statuses Codecov posts by using the following yaml configuration.
Enabling a status
Note that you can not enable a status by setting it to yes, you need to define it by using the structure described here
coverage: status: project: off patch: off
Codecov will detect changes in coverage that are NOT included in the commit/pull diff, and report these changes as a commit status.
Let's take this example to illustrate what an Unexpected Coverage Changes would look like.
As shown above, we have 100% coverage. Now let's make a change to this code base.
Our CI will run and result in the following:
Lines 1 and 2 are considered "changes" in Codecov. This status would detect these changes and report them to the commit status.
default_rules field can be added to specify some behaviors to be applied by default to every status check, unless the status check definition itself explicitly sets a different behavior.
This can be useful for setting a behavior at a global level for all checks without needing to manually go through the definition of every individual checks. This can also be useful if you want to specify a global behavior but also make exceptions for individual checks.
coverage: status: default_rules: flag_coverage_not_uploaded_behavior: exclude # this behavior will be applied to all checks by default project: projectA: flags: - projectA projectB: flags: - projectB projectC: flag_coverage_not_uploaded_behavior: include # this behavior will be applied only to this status check flags: - projectC
In this example, the
exclude behavior for the
flag_coverage_not_uploaded_behavior setting will be applied to projectA and projectB, but the
include behavior will be applied to projectC because that project's YAML configuration explicitly sets a different value for that setting.
Not all the status check configuration options can be set at a global level like this with
default_rules. Currently only the following fields are supported:
