A genealogical DNA test looks at a person's genome at specific locations for the purposes of determining ethnicity and genealogical relationships.
Results give information about ethnic groups family the tested may be descended from and about other individuals that they may be related to. In general, they do not give information about medical conditions or diseases.
Most humans want to know and be assured of their roots. DNA test to determine genealogical heritage has helped lots of people both psychologically and in other ways. This is because it has helped some to know there beginnings and enhances the sense of belonging which happens to be a basic human factor. The African-American movement to discover and identify with ancestral tribes has burgeoned since DNA testing became available and so many (especially public, historical figures) have been recipients of this test.
Y-DNA and MtDNA (results come from historical persons whose mitochondrial DNA has been tested; it identifies direct maternal ancestry, which is just one line out of many) testing may be able to determine with which peoples in present-day Africa a person shares a direct line of part of his or her ancestry, but patterns of historic migration and historical events cloud the tracing of ancestral groups.
Testing company African Ancestry maintains an "African Lineage Database" of African lineages from 30 countries and over 160 ethnic groups. Due to joint long histories in the US, approximately 30% of African American males have a European Y-Chromosome haplogroup.
I can suffice to say Africans (Black People) have been a beneficiary of the DNA test, or maybe a victim? If one thinks of genealogical DNA (ancestral) test what comes to mind mostly are African-Americans!
There are two kinds of tests: 
  1. admixture tests and
  2. lineage tests. 
Admixture tests tell you how much of your DNA comes from different parts of the world. For Black Americans it generally comes out something like this: 
77% Black Africa 
21% White Eurasia 
2% Native America 
According to authorities like Salas, nearly three-quarters of the ancestors of African Americans taken in slavery came from regions of West Africa. 
African Americans usually cannot easily trace their ancestry during the years of slavery through surname research, census and property records, and other traditional means. Genealogical DNA testing may provide a tie to regional African heritage.
Here is a list of some Black people living and deceased, who have had their DNA tested;
Oprah Winfrey
became the biggest celebrity to have her DNA analyzed. Appearing on the PBS documentary African American Lives, Winfrey’s genetic make up revealed a predominance of sub-Saharan African DNA.

Genealogical DNA tests have become popular due to the ease of testing at home and their usefulness in supplementing genealogical research. Genealogical DNA tests allow for an individual to determine with high accuracy whether he or she is related to another person within a certain time frame, or with certainty that he or she is not related. DNA tests are perceived as more scientific, conclusive and expeditious than searching the civil records.
