How to properly test a Devextreme table?

Question

Vue.js

Testing dataGrid devextreme, via vue-test. When mounting the wrapper, the passed data: dataSource and column names are not displayed immediately after mounting. The project has adjacent tables on bootstrap, there are no such problems. Now I have done it with a crutch with setTimeout 50ms, after that the data appears. Everything is correct. Has anyone encountered a similar feature? how did you decide?
And when column names are specified they are ignored by the table and caption is set to dataField. So who faced? and how did you treat it?

Answer 1

With these data, the solution turned out to be quite simple, instead of using setTimeout, use fakeTimeout of the sinon library.
