2 years ago It looks like something in the javascript is causing this issue because the following example using curl shows this is not happening:
$ curl -X PUT 'localhost:1080/mockserver/expectation' \
-d '{

from expectation:
f971a79d-4c8a-4b8d-a04b-2b31d30e5f6aIt looks like node is doing this conversion because when I create a JSON object with a large number it is converted to the exponent form, as follows:
One way to solve this is as follows:
Number.prototype.toFixedSpecial = function(n) {
var str = this.toFixed(n);
if (str.indexOf('e+') === -1)
return str;
// if number is in scientific notation, pick (b)ase and (p)ower
str = str.replace('.', '').split('e+').reduce(function(b, p) {
return b + Array(p - b.length + 2).join(0);
});
if (n > 0)
str += '.' + Array(n + 1).join(0);
return str;
};
var mockServerClient = require('mockserver-client').mockServerClient;
let largeNumber = 1000000000000100000001;
let expectation = {

}
}
};
mockServerClient("localhost", 1080)

function () {

function (error) {

Describe the issue Large numbers are reduced to their exponent values.
What you are trying to do Running tests where large numbers are returned by mockserver
MockServer version 5.11.2
To Reproduce Setup the following expectation:
How you are running MockServer (i.e maven plugin, docker, etc) Docker
Code you used to create expectations
What error you saw No Error
Expected behaviour I'd expect to get back the request exactly as it's mocked. Instead, we get the exponent version of the large number.
MockServer Log This is kind of long. In my example above, I pulled out only the relevant bits to show the issue. Look for the
httpResponse.totalvalue to see the exponent version of the value.
