alpha testing related to acceptance testing. so, 
accepting testing is done in front of client or customer for 
their acceptance.

Alpha Testing is nothing but Acceptance testing.

So in Alpha testing the Client has to verify 
 The Product is developed according to their 

1.Requirement and Specification.
2.SLA(Service Level Agreement) i.e Time Line 
3.DRE (Defect Rate Efficiency)<0.8 DRE = DRE=A/A+B = 0.8
A = Testing Team (Defects by testing team)
B = customer     (    "    "    customer   )

If DRE <=0.8 then good product otherwise not.

If client is missing any thing and they are giving a green 
signal to the product then later on if they are getting any 
error then the product has to come in a new cycle again.

In alpha testing, there in no need of customer. Customers 
are required in beta testing.

Alpha Testing: Simulated or actual operational testing at 
an in-house site not otherwise involved with the software 
developers.

Alpha Testing: Testing software in the developer site 
by the customer after 80% - 90% completion of developing 
the application.

alpha testing:
it is a kind of user acceptance test  performed at the 
development site by the test engineers in the presence of 
customer

Alpha testing :When the project is said to be in completion 
it is said to alpha testing .Minor changes  can be made at 
the end of this testing .It is done in  front of 
developers , tester 

alpha testing is conducted by the client at the developers 
site

Alpha testing is the software prototype stage when the 
software is first able to run. It will not have all the 
intended functionality, but it will have core functions and 
will be able to accept inputs and generate outputs. An 
alpha test usually takes place in the developer's offices 
on a separate system.

alpha testing is nothing but testing of application by user 
at developer site,under the monitoring of developer.

Alpha testing is being done by both end user and the developer.
Beta testing is done by the end user.Developer is not
present there.

Testing after code is mostly complete or contains most of 
the functionality and prior to users being involved. 
Sometimes a select group of users are involved. More often 
this testing will be performed in-house or by an outside 
testing firm in close cooperation with the software 
engineering department.

In this testing process testers will verify the app in the 
presence of the End-users(client) with in the organization 
enviroment. It is also know as Off-site testing.

Alpha Testing is only done by the development end.In this 
testing there is no need of client.We check the product 
that it is according to the client requirements or not.

Alpha testing is done in the same company but differnt 
group of testers from the actual testing group who were
