Router Integration Tests

This directory contains integration tests for the router. It is a separate package to prevent dependencies of the tests and demos from becoming dependencies of github.com/wundergraph/cosmo/router.

Updating the demo subgraphs

Regenerate the router execution config with ./update-config-no-edg.sh. This will propogate any changes from the SDLs.

Running the tests

go test -race -v ./...

It can take a while until the tests finish.

Updating fixtures

Some of the tests uses the goldie based snaphots

In case you need to update all snaphots, you can run the following command:

go test -update ./...

Be aware that this will overwrite all snaphots with the current output of the tests. Use this command with caution.

Alternatively you can update a single snaphot by temporarily replacing call to g.Assert with g.Update in the test and running the test.

Functions

func AssertAttributeNotInSet

func AssertAttributeNotInSet(t *testing.T, set attribute.Set, attr attribute.KeyValue)

func GetMetricByName

func GetMetricByName(scopeMetric *metricdata.ScopeMetrics, name string) *metricdata.Metrics
