=~expect语法的rspec错误不支持运算符匹配器

得到

因为代码是

The expect syntax does not support operator matchers, 
so you must pass a matcher to `#to`.

我想换的

class_methods.all.should =~ [:bar, :hello]

我也试过了

expect(class_methods.all).to =~ [:bar, :hello]

expect(class_methods.all).to match [:bar, :hello]

及

及

我相信数组的

=~

的替换是可行的

需要明确的是，per，而新的

expect

语法支持多种比较运算符（例如

），您可以尝试：

expect(class_methods.all).to match_array [:bar, :hello]

expect(class_methods.all match([:bar, :hello])).to be_true
# this one gives wrong number of arguments

expect(class_methods.all).to match_array [:bar, :hello]

subject { class_methods.all }

it { should match_array [:bar, :hello] }
