I have the following React components, and I want to select one of the selectElements in my select-block with TestUtils. How do I do that?
var selectElements = ["type_a", "type_b"];
var SelectElement = React.createClass({
render: function() {
return (
<option value={this.props.type}>{this.props.type}</option>
);
}
});
var MyForm = React.createClass({
handleSubmit: function(e) {
console.log("submitted");
},
render: function () {
var selectElements = this.props.availableTypes.map(function (type) {
return (
<SelectElement key={type} type={type} />
);
});
return (
<form role="form" onSubmit={this.handleSubmit}>
<select ref="type" name="type">
<option value="">-- Choose --</option>
{selectElements}
</select>
<input type="submit" value="Search"/>
</form>
);
}
});
I've already tried doing it like this:
var myFormComponent = TestUtils.renderIntoDocument(<MyForm selectElements={selectElements} />);
var form = TestUtils.findRenderedDOMComponentWithTag(myFormComponent, 'form');
var selectComponent = TestUtils.findRenderedDOMComponentWithTag(form, 'select');
TestUtils.Simulate.change(selectComponent, { target: { value: 'type_a' } });
TestUtils.Simulate.submit(form);
but it doesn't work.
The problem might be that Simulate.change only calls the select's onChange (which doesn't exist). I don't think it'll actually cause the select's value to change unless you cause that change in your onChange handler.
If you insist on using refs over onChange, change this line:
TestUtils.Simulate.change(selectComponent, { target: { value: 'type_a' } });
to this:
selectComponent.getDOMNode().value = 'type_a';
