TLS Client Certificates

Playwright now allows to supply client-side certificates, so that server can verify them, as specified by TLS Client Authentication.

You can provide client certificates as a parameter of browser.new_context() and api_request.new_context(). The following snippet sets up a client certificate for https://example.com:

context = browser.new_context(
    client_certificates=[
        {
            "origin": "https://example.com",
            "certPath": "client-certificates/cert.pem",
            "keyPath": "client-certificates/key.pem",
        }
    ],
)

When using the Pytest plugin, it can be added like this:

@pytest.fixture(scope="session")
def browser_context_args(browser_context_args):
    return {
        **browser_context_args,
        "client_certificates": [
            {
                "origin": "https://example.com",
                "certPath": "client-certificates/cert.pem",
                "keyPath": "client-certificates/key.pem",
            }
        ],
    }
