Schema - TestAsync
The .testAsync method performs the same functionality as .test, but works asynchronously, allowing for validation of values returned by Promises.
Syntax
.testAsync(value: any, valueName: string): Promise<Tests>- value: The value or a Promise of the value to be validated.
- valueName: A string used to reference the value in the validation output.
Example
The following example demonstrates how to use .testAsync to validate a value asynchronously:
import { schema } from "vkrun"
const schema = schema().number().float()
const valueA = async (): Promise<number> => {
return await new Promise((resolve) => {
setTimeout(() => {
resolve(123.5)
}, 100)
})
}
const valueA = async (): Promise<number> => {
return await new Promise((resolve) => {
setTimeout(() => {
resolve(123)
}, 100)
})
}
const testA = await schema.testAsync(valueA(), "value_name")
const testB = await schema.testAsync(valueB(), "value_name")Output testA:
{
passedAll: true,
passed: 3,
failed: 0,
totalTests: 3,
successes: [
{
method: "required",
name: "value_name",
expect: "value other than undefined",
received: 123.5
},
{
method: "number",
name: "value_name",
expect: "number type",
received: 123.5
},
{
method: "float",
name: "value_name",
expect: "float type",
received: 123.5
}
],
errors: [],

}Output testB:
{
passedAll: false,
passed: 2,
failed: 1,
totalTests: 3,
successes: [
{

name: "value_name",
expect: "value other than undefined",

},
{

expect: "number type",
received: 123
}
],
errors: [

name: "value_name",
expect: "float type",
received: 123,
message: "value_name must be a float!"
}
],
