test: check tls server verification with addCACert

sam-github · Italo A. Casas · commit b77b1bb43cee · 2017-01-22T22:14:32.000-05:00
SecureContext.addCACert() adds to the existing root store, preserving root cert entries. option.ca is applied without calling SecureContext.addRootCerts() so should add to the default, empty, root store. This test confirms that the built-in root CAs are not included when options.ca is used.
