[英]Grails Interceptor model is null in unit test
我有一個攔截器,可以在模型對象上設置屬性。 在單元測試中,模型為空。
攔截器
import groovy.transform.CompileStatic
import groovy.util.logging.Commons
@CompileStatic
@Commons
class FooInterceptor {
FooInterceptor() {
matchAll()
}
boolean after() {
model.foo = 'bar'
true
}
}
規格
import grails.test.mixin.TestFor
import spock.lang.Specification
@TestFor(FooInterceptor)
class FooInterceptorSpec extends Specification {
void "Test Foo interceptor loads var to model"() {
when: "A request matches the interceptor"
withRequest(controller: 'foo', action: 'index')
interceptor.after()
then: "The interceptor loads the model"
interceptor.doesMatch()
interceptor.model.foo == 'bar'
}
}
堆棧跟蹤
Cannot set property 'foo' on null object
java.lang.NullPointerException: Cannot set property 'foo' on null object
at bsb.core.web.FooInterceptor.after(FooInterceptor.groovy:13)
at bsb.core.web.FooInterceptorSpec.Test Foo interceptor loads var to model(FooInterceptorSpec.groovy:9)
在Spec中設置ModelAndView請求屬性可以為我們解決問題:
import grails.test.mixin.TestFor
import spock.lang.Specification
@TestFor(FooInterceptor)
class FooInterceptorSpec extends Specification {
void "Test Foo interceptor loads var to model"() {
given:
interceptor.currentRequestAttributes().setAttribute(GrailsApplicationAttributes.MODEL_AND_VIEW, new ModelAndView('dummy', [:]), 0)
when: "A request matches the interceptor"
withRequest(controller: 'foo', action: 'index')
interceptor.after()
then: "The interceptor loads the model"
interceptor.doesMatch()
interceptor.model.foo == 'bar'
}
}
