v1.46.0

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.NewContextAsync() and APIRequest.NewContextAsync(). The following snippet sets up a client certificate for https://example.com:

var context = await Browser.NewContextAsync(new() {
  ClientCertificates = [
    new() {
      Origin = "https://example.com",
      CertPath = "client-certificates/cert.pem",
      KeyPath = "client-certificates/key.pem",
    }
  ]
});

When using the MSTest or NUnit base-classes, these can be added by using the ContextOptions method.
