# hashr
Hashr is a tiny class makes test on JSON response easier.
The name of `hashr` come from the awesome ruby gem [hashr](https://github.com/svenfuchs/hashr), though, AFAIK, use original code is not possible because Crystal very different with Ruby in some aspect.
This shard should only be used in spec.
## Installation
1. Add the dependency to your `shard.yml`:
```yaml
dependencies:
hashr:
github: crystal-china/hashr
```
2. Run `shards install`
## Usage
Following is a example use graphql + spec-kemal
```crystal
require "hashr"
require "../spec_helper"
describe "daily reports" do
it "query daily report" do
report = ReportFactory.create
post_json "/graphql", body: {query: "query { ... }"}
p! typeof(response.body) # => String
p! response.body # => "{\"data\":{\"reportQuery\":{\"target\":{\"targetTotalCount\":47,\"processedTotalCount\":44,\"qualifiedTotalCount\":40}}}}"
response_hash = Hash(String, JSON::Any).from_json(response.body) # => Get a hash like this:
# {"data" => {
# "reportQuery" => {
# "target" => {
# "targetTotalCount" => report.target_total_count,
# "processedTotalCount" => report.processed_total_count,
# "qualifiedTotalCount" => report.qualified_total_count
# }
# }
# }
# }
# Instead, verify on the entire response result, we can verify on specified field only.
parsed_response = Hashr.new(response)
# Use nice dot method call.
target = parsed_response.data.reportQuery.target
target.processedTotalCount.should eq report.processed_total_count
target.qualifiedTotalCount.should eq report.qualified_total_count
end
end
```
You can use Hashr as model object, like this:
```crystal
it "use hashr as model object" do
contacts = [
{
id: 1,
first: "billy",
last: "zheng",
phone: "18612385678",
email: "[email protected]",
},
{
id: 2,
first: "xuan",
last: "zheng",
phone: "18512345678",
email: "[email protected]",
},
]
models = contacts.map { |e| Hashr.new(e) }
models.each do |contact|
puts "#{contact.first}.#{contact.last}: phone: #{contact.phone}, email: #{contact.email}"
end
billy = models.first
billy.phone = "13012345678"
p billy.name # => 13012345678
```
## Limit
For verify a value is nil, you have to use `eq`, `be_nil` not work because Crystal don't allow us redefine #nil? method on any object.
```crystal
h = {"nilValue" => nil}.to_json
value = Hashr.new({"foo" => JSON.parse(h)})
value.foo.nilValue.should eq nil # => true
value.foo.nilValue.should be_nil # => false
```
