Assert.IsNot¶

Name	Mandatory	Description	Default	Type
`⬅️ Input`		The input can be of any type.		`Any`
`Output ➡️`		The output will be the input (passthrough).		`Any`
`Value`	No	The value to test against for equality.	`none`	`Any`
`Break`	No	If we should trigger a debug breakpoint on failure.	`false`	`Bool`

This assertion is used to check whether the input is different from a given value.

Details¶

In this shard it's the inequality that's asserted. This means the assertion is considered successful if input to this shard does not match the :Value parameter of this shard.

The rest of behaviour of this shard (including the impact of the value of the :Break parameter) is identical to Assert.Is.

Just like Assert.Is, this shard too can be used for writing (inline) unit test cases.

Examples¶

Code

; :Break = `true`, assertion true
; => log no errors and dont abort program
8 | Assert.IsNot(16 Break: true)

Code

; :Break = `true`, assertion false
; => abort the program
8 | Maybe({
  Assert.IsNot(8 Break: true)
})

[error] Failed assertion IsNot, input: 8 not expected: 8
[error] Assert.IsNot -> Error: Assert failed - IsNot, Line: 4, Column: 3
[warning] Maybe shard Ignored an error: Assert failed - IsNot, line: 3, column: 5, wire: sample-wire

Code

; :Break = `false`, assertion true
; => log no errors and dont abort program
8 | Assert.IsNot(16 Break: false)

Code

; :Break = `false`, assertion false
; => log assertion error but dont abort program
8 | Maybe({
  Assert.IsNot(8 Break: false)
})

[error] Failed assertion IsNot, input: 8 not expected: 8
[error] Assert.IsNot -> Error: Assert failed - IsNot, Line: 4, Column: 3
[warning] Maybe shard Ignored an error: Assert failed - IsNot, line: 3, column: 5, wire: sample-wire
