Line 54 in 6690a49

throw new GraphQlAuthenticationException(__($e->getMessage()), $e);

graphql-ce/app/code/Magento/CustomerGraphQl/Model/Customer/CheckCustomerPassword.php

Line 56 in 6690a49

throw new GraphQlNoSuchEntityException(__($e->getMessage()), $e);

throw new GraphQlAuthenticationException(__($e->getMessage()), $e);

Test case "Try to change customer password when customer's account is locked" is already covered in dev/tests/api-functional/testsuite/Magento/GraphQl/Customer/ChangeCustomerPasswordTest.php::testChangePasswordIfCustomerIsLocked()

throw new GraphQlNoSuchEntityException(__($e->getMessage()), $e);

Impossible to cover this case. Because customer's token is assigned to particular customer ID (see oauth_token.customer_id). So, if we have a token then we have an ID of existing customer.

throw new GraphQlInputException(__($e->getMessage()), $e);

It will never appear because we have input params validations in app/code/Magento/CustomerGraphQl/Model/Resolver/ChangePassword.php and these cases already covered in dev/tests/api-functional/testsuite/Magento/GraphQl/Customer/ChangeCustomerPasswordTest.php.

I've created a PR #995 that removes unnecessary exceptions in Magento\CustomerGraphQl\Model\Customer\CheckCustomerPassword.
