ruby - Ruby，FuzzBert，无法将 Proc 转换为字符串（TypeError）

Question

我正在尝试使用 FuzzBert，但我无法使随机生成器工作。

此示例来自官方存储库 ：

require 'fuzzbert'

fuzz "Web App" do
  deploy do |data|
    #send JSON data via HTTP
  end

  data "template" do
    t = FuzzBert::Template.new <<-EOS
      { user: { id: ${id}, name: "${name}" } }
    EOS
    t.set(:id) { FuzzBert::Generators.cycle(1..10000) }
    t.set(:name) { FuzzBert::Generators.random }
    t.generator
  end
end

当我运行它（fuzzbert myfile.rb）时，我遇到了这个错误：

fuzzbert-1.0.1/lib/fuzzbert/template.rb:17:in `block (2 levels) in to_data': can't     convert Proc into String (TypeError)

我试过撬解释器，我有同样的错误：

> t = FuzzBert::Template.new '{ user: { name: "${name}" } }'
> t.set(:name) { FuzzBert::Generators.random }
> t.to_data
TypeError: can't convert Proc into String
from /home/you/.rbenv/versions/1.9.3-p327-perf/lib/ruby/gems/1.9.1/gems/fuzzbert-1.0.1/lib/fuzzbert/template.rb:17:in `block (2 levels) in to_data'

我该如何解决？

Unfortunately, this was simply a bug. It has been fixed and I also released a new version 1.0.3 with updated examples. The above example would now be written as

require 'fuzzbert'

fuzz "Web App" do
  deploy do |data|
    #send JSON data via HTTP
  end

  data "template" do
    t = FuzzBert::Template.new <<-EOS
      { user: { id: ${id}, name: "${name}" } }
    EOS
    t.set(:id, FuzzBert::Generators.cycle(1..10000))
    t.set(:name, FuzzBert::Generators.random)
    t.generator
  end
end
