reactjs - GraphQL query does not update on react router v4 history push -


i implement basic filtering option in react web app. have 3 components

videolist --------------------------  filter    result  --------  ---------------- category

the filter component , result component both children of videolist component. in filter component when user clicks on category, pushing new url, this.props.history.push(/videos/${category.name}). seems react-router settings works correctly , videolist component gets new category name , passes result component.

<route exact path="/videos" component={videolist}/>, <route exact path="/videos/:category" render={props => <videolist {...props} />} />,

in videolist component

<result category={category} />

the result component makes usage of new category name in own graphql query follow:

export default compose(   graphql(videos_query, {     options: props => {        return {         variables: {           filterbycategory: props.category ? props.category : null,               }       };     }, ...

but, unknown me reasons when pushing new url first time props.data.videoquery (this return values graphql server) in result component gets undefined. however, when user clicks on category second time, result components renders correctly.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
