I'm trying to unit test onClick the state of the props in my component clear.
I tried doing it this way:
props = {
attributeTableData: data,
clearMessage: onClickMethod,
reset: () => { },
resetAttributeTable: () => { },
statusMessage: {
messageType: 'message-success',
userMessage: 'Template has been saved successfully. Please wait …see your results display with the latest'
},
submitTemplateCreationStatus: () => { },
templateAttributeFormData: () => { },
templateFormSubmission: true,
templateAttributeFormSubmission: true,
templateFormData: () => { },
userRoles: new Set(['admin'])
};
let emptyStatusMessage = {};
actualComponent = shallow(<CreateTemplateResults { ...props } />);
actualComponent.instance().resetForms();
expect(onClickMethod.called).to.be.true;
expect(actualComponent.state('statusMessage')).to.eql(emptyStatusMessage)
But I get:
" TypeError: ShallowWrapper::state("statusMessage") requires that
state
not benull
orundefined
"
You are creating a shallow render of <CreateTemplateResults />
, but never passing actualComponent.setState(nextState)
. Therefore, when you are trying to access the state on your last line, it is throwing an error because state is null
/ undefined
.
