What is Black Box Testing ?

It is way of Software testing where the code or program is not known to tester

[{"selector":"#anim-d81448d2-8d04-467c-93a7-ee97a38b4882","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3a32d7bb-e8a8-4a2c-9c3b-5ceb85685d57","keyframes":{"transform":["translate3d(-100%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Black Box testing can be done based on the software requirement document

[{"selector":"#anim-ff0d81ec-f148-4972-9f20-07b7e26abf5e","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-371a9af2-cfe5-420d-bf9c-70e6406fe637","keyframes":{"transform":["translate3d(100.24331%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Its aim is to test if software is developed and is behaving as per the requirements

[{"selector":"#anim-59b57795-33dd-49b3-ab41-0111c5ef6fcb","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-a2d4fc61-2777-4043-950d-624931c3913b","keyframes":{"transform":["translate3d(-100%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Mainly focuses on input and output of the software applications

[{"selector":"#anim-663a0cb9-7800-4718-8155-a63520613c2a","keyframes":{"transform":["translate3d(100.24331%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-737fc841-33a7-4602-96c5-0cfb1a8bdaf4","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-612dafb4-696d-4fb1-b087-0f94f63cb802","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Tester need not know how the coding is done

[{"selector":"#anim-7eb806b9-9c9a-41cb-926a-8a45685e2e65","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-77c56072-03db-4af3-a572-b9f27d2f2997","keyframes":{"transform":["translate3d(99.75787%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Types of Black Box Testing: 1.Functional Testing 2. Non-Functional Testing 3. Regression Testing

[{"selector":"#anim-85f0009c-9c27-43d3-8fc1-c0a715203990","keyframes":{"transform":["translate3d(-100%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-be51701b-889d-490a-8f90-8b006ca14b9c","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-cc140ce5-7561-45b4-b242-9e6fe9d4f364","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Opposite to Black Box testing is White Box Testing ,where tester should have programming knowledge to test software
