- message type.public class ProtoSubject<S extends ProtoSubject<S,M>,M extends com.google.protobuf.Message> extends LiteProtoSubject<S,M> implements ProtoFluentAssertion
ProtoTruth.assertThat(actual).isEqualTo(expected)
performs the same assertion as
Truth.assertThat(actual).isEqualTo(expected)
, but with a better failure message. By
default, the assertions are strict with respect to repeated field order, missing fields, etc.
This behavior can be changed with the configuration methods on this subject, e.g. ProtoTruth.assertThat(actual).ignoringRepeatedFieldOrder().isEqualTo(expected)
.
Floating-point fields are compared using exact equality, which is probably not what you want if the values are the results of some arithmetic. Support for approximate equality may be added in a later version.
Equality tests, and other methods, may yield slightly different behavior for versions 2 and 3 of Protocol Buffers. If testing protos of multiple versions, make sure you understand the behaviors of default and unknown fields so you don't under or over test.

Specifies that, for all repeated and map fields, any elements in the 'actual' proto which are
not found in the 'expected' proto are ignored, with the exception of fields in the expected
proto which are empty.

Specifies that the 'has' bit of individual fields should be ignored when comparing for
equality.

ignoringRepeatedFieldOrder()
Specifies that the ordering of repeated fields, at all levels, should be ignored when comparing

isEqualTo(Object expected)
Checks whether the MessageLite is equivalent to the argument, using the standard equals()
implementation.
|
void |
isNotEqualTo(Object expected)
Fails if the subject is equal to the given object.
|
ProtoFluentAssertion |
reportingMismatchesOnly()
If set, in the event of a comparison failure, the error message printed will list only those
specific fields that did not match between the actual and expected values.

Compares double fields as equal if they are both finite and their absolute difference is less

public ProtoFluentAssertion ignoringFieldAbsence()
ProtoFluentAssertion
For version 2 Protocol Buffers, this setting determines whether two protos with the same
value for a primitive field compare equal if one explicitly sets the value, and the other
merely implicitly uses the schema-defined default. This setting also determines whether unknown
fields should be considered in the comparison. By ignoringFieldAbsence()
, unknown
fields are ignored, and value-equal fields as specified above are considered equal.
For version 3 Protocol Buffers, this setting has no effect. Primitive fields set to their default value are indistinguishable from unset fields in proto 3. Proto 3 also eliminates unknown fields, so this setting has no effect there either.
ignoringFieldAbsence
in interface ProtoFluentAssertion
public ProtoFluentAssertion ignoringRepeatedFieldOrder()
ProtoFluentAssertion
This setting applies to all repeated fields recursively, but it does not ignore structure.
For example, with ProtoFluentAssertion.ignoringRepeatedFieldOrder()
, a repeated int32
field bar
, set inside a repeated message field foo
, the following protos will all compare
equal:
message1: {
foo: {
bar: 1
bar: 2
}
foo: {
bar: 3
bar: 4
}
}
message2: {
foo: {
bar: 2
bar: 1
}
foo: {
bar: 4
bar: 3
}
}
message3: {
foo: {
bar: 4
bar: 3
}
foo: {
bar: 2
bar: 1
}
}
However, the following message will compare equal to none of these:
message4: {
foo: {
bar: 1
bar: 3
}
foo: {
bar: 2
bar: 4
}
}
This setting does not apply to map fields, for which field order is always ignored. The serialization order of map fields is undefined, and it may change from runtime to runtime.

ProtoFluentAssertion
ProtoFluentAssertion.comparingExpectedFieldsOnly()
.
This rule is applied independently from ProtoFluentAssertion.ignoringRepeatedFieldOrder()
. If ignoring
repeated field order AND extra repeated field elements, all that is tested is that the expected
elements comprise a subset of the actual elements. If not ignoring repeated field order, but
still ignoring extra repeated field elements, the actual elements must contain a subsequence
that matches the expected elements for the test to pass. (The subsequence rule does not apply
to Map fields, which are always compared by key.)

ProtoFluentAssertion
The "expected proto(s)" are those passed to the void method at the end of the ProtoFluentAssertion
call-chain: For example, ProtoFluentAssertion.isEqualTo(Object)
, or ProtoFluentAssertion.isNotEqualTo(Object)
.
Fields not set in the expected proto(s) are ignored. In particular, proto3 fields which have their default values are ignored, as these are indistinguishable from unset fields. If you want to assert that a proto3 message has certain fields with default values, you cannot use this method.

This method adds on any previous FieldScope
related settings, overriding previous
changes to ensure the specified fields are ignored recursively. All sub-fields of these field
numbers are ignored, and all sub-messages of type M
will also have these field numbers
ignored.
If an invalid field number is supplied, the terminal comparison operation will throw a runtime exception.
