ActionView::Template::Error: while running rspec in groups or file

Question

I am working on view specs using RSpec. When I use render in it block. Then my first test case is passed but 2nd one is saying the error.

Failure/Error: render
ActionView::Template::Error:
       undefined method `__abc_edit_html_erb___2948629399434343193_79820' for #<#<Class:0x000000000a357488>:0x000000000a3553b8>

it "displays the correct text Editing Device" do
    render
    expect(rendered).to match t('device.edit')
  end
  it "should have form" do 
    render
    assert_select "form"
  end
