AssertCollection: Collect multiple assertions

Description

The function makeAssertCollection() returns a simple stack-like closure you can pass to all functions of the assert*-family. All messages get collected and can be reported with reportAssertions(). Alternatively, you can easily write your own report function or customize the the output of the report function to a certain degree. See the example on how to push custom messages or retrieve all stored messages.

Usage

makeAssertCollection()
reportAssertions(collection)

Arguments

collection

[AssertCollection] Object of type AssertCollection (constructed via makeAssertCollection).

Value

• makeAssertCollection() returns an object of class AssertCollection and reportCollection returns invisibly TRUE if no error is thrown (i.e., no message was collected).

Examples

x = "a"
coll = makeAssertCollection()

print(coll$isEmpty())
assertNumeric(x, add = coll)
coll$isEmpty()
coll$push("Custom error message")
coll$getMessages()
reportAssertions(coll)
