vcr
VCR for Crystal!
Record your test suite's HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests.
Example reduction in test time with over 2k RESTful requests:
Without VCR
Finished in 10:22 minutes
18 examples, 0 failures, 0 errors, 0 pending
With VCR
Finished in 13.05 seconds
18 examples, 0 failures, 0 errors, 0 pending
Notes:
The idea of this port is to keep it simple and allow multiple requests to be recorded within a single "cassette" block. The ability to record changed requests to the same endpoint is also important and unavailable in other vcr ports. I have also tried to keep the syntax and methods as close to the Ruby VCR to help.
Other VCR like ports:
Installation
Add this to your application's shard.yml:
development_dependencies:
vcr:
github: spoved/vcr.cr
Usage
require "vcr"
require "http/client"
load_cassette("cassette-one") do
response = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos/1")
end
You can also record multiple requests within a single block:
load_cassette("cassette-two") do
r1 = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos/1")
r2 = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos/2")
end
To easily reset the cassette and record, simply add the :record argument:
load_cassette("cassette-two", :record) do
r1 = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos/1")
r2 = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos/2")
end
To record difference in the same response add the :in_order argument. This Will
record and play back the VCR in order the requests occurred (recording new ones if missing).
VCR.use_cassette("cassette-one", :record, :in_order) do
r1 = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos")
HTTP::Client.delete("https://jsonplaceholder.typicode.com/todos/1")
r2 = HTTP::Client.get("https://jsonplaceholder.typicode.com/todos")
end
Customize the location of where the cassettes are stored. The default is spec/fixtures/vcr.
VCR.configure do
settings.cassette_library_dir = "/some/path/cassettes"
end
Sensitive data can be filtered out via the filter_sensitive_data setting (thanks mmacia!):
VCR.configure do |settings|
settings.filter_sensitive_data["api_key"] = "<API_KEY>"
end
Spec usage
Add a hook to load a cassette before the whole suite or use before_each inside your context
Spec.before_suite { load_cassette("my-spec-cassette", :record) }
