The test array

When you retrieve scan results, the response includes a tests array. Each entry in that array corresponds to one of the tests documented below, with a name, value, result, and attributes.

Display tests

This section lists every display test that Advalidation can run against a creative. Each test checks one aspect of the creative and returns pass, fail, or warn.

Test_Display_AdDimensions

Checks if the creative’s pixel dimensions match one of the accepted ad unit sizes defined in the ad specification.

Result	Condition
pass	Dimensions match an accepted size
fail	Dimensions do not match any accepted size

Example response

{
  "name": "Test_Display_AdDimensions",
  "value": "300x250",
  "valueFormatted": "300x250",
  "valuePhrase": "300x250 matches one of the accepted dimensions.",
  "result": "pass",
  "attributes": [
    { "name": "Display_Width", "description": "Pixel width of creative", "value": 300 },
    { "name": "Display_Height", "description": "Pixel height of creative", "value": 250 }
  ]
}

Test_Display_AdVerificationTags

Detects ad verification vendor tags (DoubleVerify, IAS, MOAT, etc.) and checks whether they are set to monitor or block delivery. Blocking tags can cause impression discrepancies between your ad server and the advertiser’s reporting.

Result	Condition
pass	Only monitoring tags detected, or tags match the ad spec policy

Example response

{
  "name": "Test_Display_AdVerificationTags",
  "value": "monitoring",
  "valueFormatted": "Monitoring",
  "valuePhrase": "cdn.doubleverify.com/dvtp_src.js detected in third party tag. This allows the ad verification vendor to monitor tag performance. Only monitoring tags allowed.",
  "result": "pass",
  "attributes": [
    { "name": "Display_AdVerificationType", "description": "Display ad verification type (blocking/monitoring)", "value": "monitoring" },
    { "name": "Display_AdVerificationVendor", "description": "Display ad verification vendor", "value": "doubleverify" }
  ]
}

Test_Display_AnimationLength

Checks if the ad’s animation stops within the allowed duration. Long-running animations distract visitors and violate most publisher specifications.

Result	Condition
pass	Animation stops within the threshold (e.g., 15 seconds)
fail	Animation runs longer than allowed

Example response

{
  "name": "Test_Display_AnimationLength",
  "value": 0,
  "valueFormatted": "0 seconds",
  "valuePhrase": "The ad animates for 0 seconds. Animation must stop within 15 seconds.",
  "result": "pass",
  "attributes": [
    { "name": "Display_AnimationDuration", "description": "Animation duration in milliseconds", "value": 0 }
  ]
}

Test_Display_Audio

fail	Audio plays automatically

Example response

{
  "name": "Test_Display_Audio",
  "value": false,
  "valueFormatted": "Not detected",
  "valuePhrase": "No audio before hover detected. Audio is not allowed before hover.",
  "result": "pass",
  "attributes": [
    { "name": "Display_AudioBeforeHover", "description": "Audio before hover", "value": false },
    { "name": "Display_AudioAfterHover", "description": "Audio after hover", "value": false }
  ]
}

Test_Display_Border

Checks if the creative has a distinct border that visually separates it from page content. This is a common publisher requirement to prevent ads from blending into editorial content.

Result	Condition

  "value": true,
  "valueFormatted": "Indistinct border",

    { "name": "Display_LowContrastBorder", "description": "Low contrast border", "value": true }
  ]
}

Test_Display_ClickRedirects

  "result": "pass",
  "attributes": [
    { "name": "Display_ClickRedirects", "description": "Redirects on click", "value": 1 }
  ]
}

Test_Display_CodeRules

Validates the creative’s source code against custom rules defined in the ad specification. These rules can check for prohibited code patterns, required scripts, or other code-level requirements.

  "attributes": [
    { "name": "Display_TotalCookies", "description": "Number of cookies", "value": 0 }
  ]
}

Test_Display_Cpu

Measures the creative’s CPU usage as average and peak percentages. High CPU usage drains battery life and degrades the browsing experience, especially on mobile devices.

fail	Average or peak exceeds the threshold

Example response

{
  "name": "Test_Display_Cpu",
  "value": 1,

    { "name": "Display_CPUPeak", "description": "CPU peak", "value": 4 }
  ]
}

Test_Display_ExternalRequests

Result	Condition
pass	Request count within limit
fail	Too many requests

Example response

{
  "name": "Test_Display_ExternalRequests",
  "value": 5,
  "valueFormatted": 5,

    { "name": "Display_FileRequestsInitial", "description": "Initial requests (post exclusions)", "value": 4 }
  ]
}

Test_Display_Filesize

Example response

{
  "name": "Test_Display_Filesize",
  "value": "141977",
  "valueFormatted": "139 kb",
  "valuePhrase": "The hosted filesize of this ad is 139 kb. The maximum hosted filesize allowed is 100 kb.",

  "valuePhrase": "This creative's code contains the GDPR consent macro.",
  "result": "pass",
  "attributes": []
}

Test_Display_HeavyAdInterventions

Checks if the creative would trigger Chrome’s heavy ad intervention, which removes ads that consume excessive CPU or network resources. Chrome considers an ad “heavy” if it uses more than 4 MB of network, more than 15 seconds of CPU in any 30-second window, or more than 60 seconds of CPU total.

Result	Condition
pass	Resource usage within Chrome’s limits
fail	One or more thresholds exceeded

Example response

  "attributes": [
    { "name": "Display_LandingPageResponseCode", "description": "Landing page HTTP code", "value": 200 }
  ]
}

fail	Local storage objects detected

Example response

{
  "name": "Test_Display_LocalStorage",
  "value": false,
  "valueFormatted": "Not detected",

Example response

{
  "name": "Test_Display_TagLoadInitial",
  "value": "35091",

  ]
}

Test_Display_TagLoadSubload

Measures the total file size of assets loaded during the subload phase (after the browser’s load event). Subload has a higher budget than initial load since the page has already rendered.

  ]
}

Test_Display_VisualStart

Measures how quickly the creative renders visible content. Slow-loading ads get scrolled past before they are seen, directly impacting viewability metrics and campaign performance.

Result	Condition

Example response

{
  "name": "Test_Display_VisualStart",
  "value": "664",
  "valueFormatted": "0.66 seconds",
  "valuePhrase": "The median visual start time was 0.66 seconds. Ads must render something visible within 0.8 seconds.",
  "result": "pass",
  "attributes": [
    { "name": "Display_VisualStartTime", "description": "Time to visual start in milliseconds", "value": 664 }
  ]
}

Video tests

This section lists every video test that Advalidation can run against a creative. Each test checks one aspect of the video or VAST tag and returns pass or fail.
