## signal_composer_BasicAPITest_addObjectsDirect_InvalidSignal

API : signal-composer

Verbs : addObjects

```Lua
signals=  {
    {
        uid=  "invalidSignal",
        event=  "txc/invalidSignal",
        retention=  -1,
        unit=  "invalidSignal",
        getSignalsArgs=  {
            event=  "invalidSignal"
        },
        onReceived=  {
            action=  "lua://convert#_Unit_Converter",
            args=  {
                from=  "km/h",
                to=  "mi/h"
            }
        }
    }
}
```

The binding is still able to add this signal even with a negative retention and randomly filled fields.

## signal_composer_BasicAPITest_addObjectsDirect_MissingField

API : signal-composer

Verbs : addObjects

```Lua
signals=  {
    {
        event=  "txc/invalidSignal2",
        retention=  30,
        unit=  "km/h",
        getSignalsArgs=  {
            event=  "vehicle_speed"
        },
        onReceived=  {
            action=  "lua://convert#_Unit_Converter",
            args=  {
                from=  "km/h",
                to=  "mi/h"
            }
        }
    }
}
```
The binding is still able to add this signal even without an uid and then it crashes the binder.
