unit-testing - 在grails中的taglib的单元测试期间，属性为空

Question

我正在尝试在taglib中测试我的代码(grails 2.0.1):

class ATagLib {
    static namespace = "s"
    def person = {attrs, body -> out << attrs.person;}
}

@TestFor(ATagLib)
class ATagLibTests {
   @Test
   void test() {
       String p = 'Joe'
       // None of these work for me.
       assert applyTemplate('<s:person person="${p}"/>') == 'Joe'
       assert applyTemplate('<s:person/>', [person:p]) == 'Joe'
   }
}

测试总是失败，因为attrs.person为空。如何正确设置属性？

Answer 1

这将起作用:

String p = 'Joe'
assert applyTemplate('<s:person person="${person}"/>', [person:p]) == 'Joe'
assertOutputEquals('Joe is cool !', '<s:person person="${person}"/>', [person:p], { it.toString() + " is cool !" } )

它调用applyTemplate的第一个签名，即:

String applyTemplate(String contents, Map model = [:])
