+PaymentDetails buildPaymentDetailsForTest(PaymentTestDetailToChange detail, PaymentTestDataToChange data, PaymentTestModificationType modificationType, const String& valueToUse)

[Marijn Kruisselbrink, 2016/03/31 18:21:14]

What is the purpose of the modificationType parameter? This method only seems to
expect "PaymentTestOverwriteValue" as value for the parameter, so it seems there
is no need to pass it?

[please use gerrit instead, 2016/03/31 20:43:08]

I specify both PaymentTestOverwriteValue and PaymentTestRemoveKey in my test:

https://codereview.chromium.org/1753543002/diff/940001/third_party/WebKit/Sou...

If modificationType is PaymentTestRemoveKey, then a call like
item.setId("total") is never invoked. This results in absence of "id" field from
the dictionary. That is, item.hasId() will return false. The "id" field is
required. My tests verify that PaymentRequest will throw an exception if an "id"
is missing.
