我刚刚将项目的React版本升级到13.3,setProps()
不再有效。我在这个摩卡测试中使用它,我现在还不确定如何重写它。我有什么选择?
it('reloads search results when props change ', function() {
var loadResultsSpy = sinon.spy(searchView, 'loadSearchResults');
var newProps = {searchBy: 'foo', searchTerm: 'bar'};
searchView.setProps(newProps);
expect(loadResultsSpy.calledWith(newProps.searchBy, newProps.searchTerm)).toBe(true);
});

在最常见的情况下,React建议只重新渲染顶级组件,如果新渲染具有相同的组件类型,则基本上只更新道具。由于TestUtils.renderIntoDocument
只是creating a DOM node and doing a regular render into it的快捷方式,因此类似的内容将起作用(我对您的测试设置做了一些假设):
var searchView, div;
beforeEach(function() {
var comp = <SearchView searchBy="baz" searchTerm="quix" />;
div = document.createElement('div');
searchView = React.render(comp, div);
});
it('reloads search results when props change', function() {
var loadResultsSpy = sinon.spy(searchView, 'loadSearchResults');
var comp = <SearchView searchBy="foo" searchTerm="bar" />;
React.render(comp, div);
expect(loadResultsSpy.calledWith("foo", "bar")).toBe(true);
});
