+# Adding new client using the GUI
+
+## Tests for GUI settings
+* When adding a new client in the GUI, the status should default to Lead and the substatus to New Lead. (Setting: default values for those fields.)
+* Neither the status nor the substatus dropdown should not contain a placeholder option such as "None" or "Select". (Setting: Required field)
+
+
+## Tests for JS code in js/edit_client.js
+* If you change the substatus, the status should automatically change accordingly (e.g. "One-off Training" -> "Confirmed", or "3-month follow-up due" -> "Accredited"). 
+* You should not be able to change the status except by changing the substatus.
+* Initially the client type should be "-None-" and the only thing in the subtypes dropdown should be "-None-" also.
+* If you change the client type, the options in the subtype dropdown should populate accordingly (e.g. "Licensed Premises" -> a list including "Pub or Bar", or "Nightlife Organisation" -> a list including "Festival" and "Student Union")
+* The "-None-" option should always remain present in the subtypes dropdown.
+
+# Editing a client using the GUI
+## Tests for JS code in js/edit_client.js
+* The subtypes dropdown should be populated according to the existing value of the types dropdown. E.g. save a client as "licensed premises" type and reopen; the subtypes should be a list  including "Pub or Bar"
+* The status dropdown should be populated according to the existing value of the substatuses dropdown. E.g. save a client as substatus "One-off Training" and reopen; the status should be set to "Confirmed" and it should not be possible to change it.
