resources directory contains pregenerated signed exchanges and
certificate files. To run the tests in this directory,
resources/127.0.0.1.sxg.pem must be added as a trusted certificate
in your OS/browser, or your browser must be configured to ignore
errors for that certificate.
Also, these pregenerated signed exchanges and cert files are likely to
be expired, since they have short lifetime (maximum 7 days). If your
browser does not have an option to ignore certificate errors,
regenerate these files by running generate-test-sxgs.sh in the
resource directory before running the tests.
generate-test-sxgs.sh requires command-line tools in the
webpackage repository.
To install them, run:
go get -u github.com/WICG/webpackage/go/signedexchange/cmd/...
export PATH=$PATH:$(go env GOPATH)/bin
