If you get this issue  then either    the formControlName is not located on the value accessor element  or you re not importing the module for that element

You can see formControlName in label   removing this solved my problem

For UnitTest angular 2 with angular material you have to add MatSelectModule module in imports section   import   MatSelectModule   from   angular material    beforeEach async      gt        TestBed configureTestingModule         declarations    CreateUserComponent          imports    ReactiveFormsModule                  MatSelectModule          MatAutocompleteModule                        providers                          compileComponents

If you must use the label for the formControl  Like the Ant Design Checkbox  It may throw this error while running tests  You can use ngDefaultControl  lt label nz-checkbox formControlName  quot isEnabled quot  ngDefaultControl gt      Hello  lt  label gt    lt nz-switch nzSize  quot small quot  formControlName  quot mandatory quot  ngDefaultControl gt  lt  nz-switch gt

You are adding the formControlName to the label and not the input   You have this    lt div  gt     lt div class  input-field col s12  gt       lt input id  email  type  email  gt        lt label class  center-align  for  email  formControlName  email  gt Email lt  label gt     lt  div gt   lt  div gt    Try using this    lt div  gt     lt div class  input-field col s12  gt       lt input id  email  type  email  formControlName  email  gt        lt label class  center-align  for  email  gt Email lt  label gt     lt  div gt   lt  div gt    Update the other input fields as well

For anyone experiencing this in angular 9  This issue can also be experienced if you do not declare or import the component that declares your component  Lets consider a situation where you intend to use ng-select but you forget to import it Angular will throw the error  No value accessor     I have reproduced this error in the Below stackblitz demo

In my case  I used Angular forms with contenteditable elements like div and had similar problems before   I wrote ng-contenteditable module to resolve this problem

[javascript] No value accessor for form control
