Failing Unit Test

[HenKun]

Failing unit test due to wrong expectation

Preconditions

Magento 2.3.2
Enhance Smtp 1.0.7

Steps to reproduce

Run unit Test SendEmailTest::testSendEmail

Expected result

Test passes

Actual result

Test fails:

Expectation failed for method name is equal to 'addTo' when invoked 1 time(s)
Parameter 0 for invocation Magento\Framework\Mail\Template\TransportBuilder::addTo('test1@example.com', '') does not match expected value.
'test1@example.com' does not match expected type "array".

Solution

Due to issue #6 the implementation of SendEmail::sendEmail() was changed to pass $toEmail instead of [$toEmail] to the addTo() method.

So the unit test should be modified to, to expect $this->toEmail instead of [$this->toEmail]
